P1 Badge Keep the retired migration stamp repair path

Deployments stamped with 20260814_020000_merge_identity_and_warmup_heads by the retired August build can no longer start: removing this remap makes inspect_migration_state() classify the stamp as schema-ahead, and _run_upgrade_locked() raises before Alembic can upgrade it. The deleted forward repair is also needed to apply the skipped file-pin, sticky-session, account, API-key, and model-source migrations and remove the retired artifacts, so these installations require manual stamp surgery without this path.

Repair the index when file_account_pins already exists. If the table exists without ix_file_account_pins_expires_at, upgrade() returns without repairing the schema, and downgrade() later fails on the unconditional op.drop_index(). Check the index before returning and before dropping it.

P2 Badge Repair a pre-existing file-pin table's missing index

If an interrupted or partially applied file-pin migration leaves file_account_pins present but omits ix_file_account_pins_expires_at, this early return skips the remaining index creation and Alembic still stamps the revision as applied. The resulting schema continues to drift from ORM metadata, so fail-fast startup remains broken on every retry; inspect the existing table's indexes and create the missing index independently of table creation.
