3ff4fbc7e4 fix(eventstore): add owners to unique constraints (#12740)
<!-- CURSOR_AGENT_PR_BODY_BEGIN -->
# Which Problems Are Solved

Bulk unique-constraint deletes (org, IDP with many links, user, project)
reconstruct every uniqueness key in Go and emit N `DELETE`s. That can
OOM on large tenants.

A one-shot owner backfill is also not enough: during a rolling deploy,
older binaries still insert `owners = '{}'`, so a later owner-only
delete would miss those rows.

Owner-only org/user/grant delete only matches rows whose `owners` bag
contains that tag. Several grant and member types stamped the aggregate
resource owner, which is not always the user’s home org or the granted
org. Username-scope rewrites also dropped `user:` tags, so owner-only
user delete could miss rewritten username rows.

Command must not switch to owner-only delete on the first 79 of a
version, because leftover `'{}'` rows from rolling-update overlap are
only backfilled on a later 79. A failed 79 must not turn owner-delete
on, and backfill joins must not stamp the wrong org (unverified domains,
org-scoped usernames colliding with instance-scoped ones).

# How the Problems Are Solved

Uniqueness stays the existing primary key `(instance_id, unique_type,
unique_field)`. `owners` is only a lifecycle bag of tags (`org:<id>`,
`user:<id>`, `idp:<id>`, `project:<id>`, `grant:<id>`).

- Add `owners TEXT[] NOT NULL DEFAULT '{}'` on
`eventstore.unique_constraints` (init SQL for greenfield, setup 78 for
existing clusters).
- Create `unique_constraints_owners_gin` with `CREATE INDEX
CONCURRENTLY` **outside a transaction** (same pattern as step 76).
Built-in `GIN (owners)` only; no `btree_gin`.
- Stamp `WithOwners` on **add** events. Field-level removes ignore
owners. `RemoveByOwner` stores the tag in `Owners` and both v1/v3 and v2
pushers run `DELETE … WHERE instance_id = $1 AND owners @>
ARRAY[$tag]::text[]`.
- Setup 79 backfills `owners` from projections via numbered
`cmd/setup/79/*.sql` files. Table names are interpolated from
`internal/query/projection` constants. Matches use `unique_field IN (x,
lower(x))` so the primary key can be used. Missing projection tables
(`42P01`) are skipped.
- Org domains are tagged only when `is_verified`. Instance-scoped
usernames join only users that are not org-scoped (organization settings
or domain policy `user_login_must_be_domain`). Every username row still
gets `org:` + `user:` of that user.
- 79 is a **repeatable** migration. `Check` re-runs when
`lastRun["version"]` changed or when setup-only `ForceFinalize` is set
and `lastRun["finalized"]` is still false. `Finalized` is written only
after Execute succeeds.
- Failed setup events keep the last successful `lastRun`. Command reads
`finalized` only from `system.migration.repeatable.done`.
- Org / user / project remove skip N-key event replay **when that
`finalized` bit is true**. Otherwise they keep today’s N-key lists
**and** still emit `RemoveByOwner`. The “ready” result is cached in
memory once true.

Setup writes `finalized` on the 79 repeatable.done payload:

- First 79 of a version: backfill only, `finalized=false` (unless
`ForceFinalize` is already set).
- Later 79: version change or
`BackfillUniqueConstraintOwners.ForceFinalize` /
`ZITADEL_BACKFILLUNIQUECONSTRAINTOWNERS_FORCEFINALIZE` after the rolling
update is done. That run backfills leftovers and writes
`finalized=true`.

Member and grant owner bags now include every org that should delete the
row:

- Instance, org, and project members also stamp
`org:<user_resource_owner>`.
- User grants stamp grant, user, project, and granted orgs.
- Project grant members stamp the project org, user org, and granted
org.
- Project grants stamp both orgs plus `grant:<id>`. Grant remove emits
`RemoveByOwner(grant)`.
- Username-scope rewrites keep `user:<id>` as well as `org:`.
- User/grant orgs are carried as unexported add-event fields (not
persisted JSON). `WithOwners` skips empty and duplicate tags.

# Additional Changes

- Table-driven owner-tag tests, including project grant (two `org:` tags
plus `grant:`), cross-org members, user grants, and username-scope
rewrite `user:` tags.
- Table-driven 79 `Check` + `finalizeAfterSuccess` tests for version
change, sequential version bumps, ForceFinalize restart, and
already-finalized skip.
- Command tests: a failed 79 event with `finalized=true` does not enable
owner-delete.
- Integration fixtures (verified vs unverified org domain;
instance-scoped `bob` vs org-scoped `bob`).
- Instance-only and global unique types stay untagged (`'{}'`). Instance
wipe still uses `UniqueConstraintInstanceRemove`.
- Pusher owner cases live in `eventstore_pusher_owners_test.go` so
`eventstore_pusher_test.go` stays under 1k lines.

# Additional Context

A later cleanup can delete the N-key replay helpers once a release that
ran 79 a second time (or an operator who set `ForceFinalize`) is in
production. That is not required for correctness.

6082e59d47 fix(eventstore): allow overwriting resource owner of events (#12261)
# Which Problems Are Solved

- The eventstore did not support intentionally overwriting the resource
owner when creating events for aggregates that may be reused across
owners.
- Resource owner handling was implicit and could not be controlled per
command/event type.
- We needed a safe way to distinguish between:
  - keeping the existing aggregate owner, and
  - explicitly setting a new owner for specific create-like events.

# How the Problems Are Solved

- Introduced a new eventstore command type with an explicit
enforce_owner flag.
- Updated eventstore.commands_to_events and eventstore.push so owner
assignment is now explicit:
  - if enforce_owner is true, the command owner is written
- if enforce_owner is false, the existing aggregate owner is retained
when present
- Added EnforceResourceOwnerCommand and wiring so command types can opt
in to enforced owner behavior.
- Wired the new behavior through the v3 eventstore push path, including
compatibility fallback for older command type mapping.
- Added migration/setup changes to register and use the new command type
and SQL functions.
- Added and updated tests for owner overwrite and aggregate ID reuse
scenarios.

# Additional Changes

- Added small migration/setup robustness improvements related to
eventstore setup ordering and helper reuse.
- Added focused test coverage for enforced owner behavior and
sequencing.
- Events that currently allow owner changes (implement
EnforceResourceOwner) are:
  - AddedEvent (action)
  - GroupAddedEvent
  - StartedEvent (idp intent)
  - ProjectAddedEvent
  - HumanAddedEvent
  - HumanRegisteredEvent
  - MachineAddedEvent
  - CreatedEvent (schema user)

# Additional Context

- Follow-up for eventstore owner-handling correctness in create flows
and aggregate ID reuse cases.
- No additional issue link was attached for this change.
