fix(oidc): use authenticated encryption for opaque tokens (#12017)

# Which Problems Are Solved

Opaque tokens now use authenticated encryption.

# How the Problems Are Solved

- Upgrade zitadel/oidc to v3.47
- Copy crypto implementation for refresh and session tokens (internal to
zitadel)
- Added config that allows validating old tokens for gradual roll-out

# Additional Changes

- Set NX cache for `integration-test-build` to `false`, working on a
seperate fix.

# Additional Context

- closes #11315
