## Problem description
During tests we found concurrency issues in the relational table
projections. Tests got flaky if a table (e.g. organization domains) had
too many foreign keys to tables which were projected by another handler.
## Resolution
The projections of the relational tables got merged into one handler to
enforce sequential reduction of events.

## Summary
This PR introduces the relational user repository for backend v3,
including schema, repository APIs, reducers/projections, and tests for
both human and machine users.
## What changed
* Added user-focused relational migrations (users, verifications,
metadata, PATs, machine keys, passkeys, identity provider links) and
related FK wiring.
* Implemented/expanded repository domain contracts and storage
implementations for human and machine user flows.
* Added support for machine secret handling and aligned access token
type modeling.
* Extended user domain models (verifications, password/email/phone/TOTP
state, passkeys, metadata, invite handling, identity provider links).
* Updated projection/reduction coverage and integration tests for key
user lifecycle events.
* Regenerated and updated mocks/enums plus supporting database
change/column utilities.
## Notes for reviewers
* This PR is large because it establishes the foundational relational
user storage layer and related test scaffolding. Sorry for that.

# Which Problems Are Solved
In the context of moving our datastore to relational tables, Identity
Provider Intents have no definition of a relational table nor any DB API
that can be used to store the IDP intents as relational objects.
# How the Problems Are Solved
The PR follows the guidelines left in #11190
- A table `zitadel.identity_provider_intents` is created: it defines its
relational constraints (foreign keys) with the other tables, as well as
an ENUM to represent the state of the intent.
- An IDP Intent repository has been created, which offers CRUD
operations implemented as `Create`, `Get`, `Update` and `Delete` methods
for the IDP intent.
- The repository also defines all columns and conditions useful for
performing DB operations on the IDP intents.
- DB mocks have been added as well to ease testing on the `domain`
package.
- Reduction functions have been implemented for the existing IDP events
so to keep the relational table in sync with the event store.
# Additional Changes
To allow testing LDAP intent flow, the `Session.FetchUser()` method has
been extracted to a separate file. A corresponding mock has been created
as well in `fetch_user_mock.go`. The files are mutually excluded and
added at build time through go build tags: the mock is added when the
`integration` tag is specified, while the real implementation is added
when the same tag IS NOT added to the build tags.
# Additional Context
- Closes#11190
