Bug Description

simpleUpdateRecords in RecordOpenApiService calls the full computation pipeline (computed orchestrator, linkService.planDerivateByLink, commitForeignKeyChanges, batchService.updateRecords) without any transaction wrapping, timeout, or deadlock retry.

If any step fails partway through, junction table changes can be committed while JSONB updates are not, computed field evaluations can be partially applied, and __version can be corrupted due to a read-then-write race without FOR UPDATE locking.

This is inconsistent with updateRecords which wraps in $tx with bigTransactionTimeout and @retryOnDeadlock.

What This Fix Does

  • Adds @retryOnDeadlock() decorator for transient deadlock recovery
  • Wraps in $tx with bigTransactionTimeout for atomicity and timeout protection

Matches the pattern already used by updateRecords and multipleCreateRecords.

Client Information

  • OS: Linux (Docker, Google Cloud Run)
  • Database: PostgreSQL 17

Platform

Docker standalone (Google Cloud Run)

simpleUpdateRecords calls the full computation pipeline (computed
orchestrator, linkService.planDerivateByLink, commitForeignKeyChanges,
batchService.updateRecords) without any transaction wrapping, timeout,
or deadlock retry.

If any step fails partway through, junction table changes can be
committed while JSONB updates are not, computed field evaluations can
be partially applied, and __version can be corrupted due to a
read-then-write race without FOR UPDATE locking.

This is inconsistent with updateRecords which wraps in $tx with
bigTransactionTimeout and @retryOnDeadlock.

This fix adds:
- @retryOnDeadlock() decorator for transient deadlock recovery
- $tx wrapper with bigTransactionTimeout for atomicity and timeout
  protection

## Problem

The /link-fix endpoint's InvalidLinkReference repair has a race condition
under concurrent write load. The current two-step approach:

1. checkLinks() — SELECT to detect desynced record IDs
2. fixLinks(recordIds) — UPDATE only those specific records

Between steps 1 and 2, concurrent writes can:
- Create NEW desyncs not in the recordIds list (missed until next run)
- Worsen existing desyncs (JSONB changes between detection and fix)
- Overwrite the fix immediately after it's applied

In production under sustained concurrent API load (200-800 writes/hr),
we've observed full JSONB array wipes (e.g., 9,781 entries reduced to 0)
caused by the read-modify-write race in Teable's link update path. The
integrity fix endpoint, meant to repair these desyncs, is vulnerable to
the same concurrent writes because of this detection-fix gap.

## Solution

Add atomicFixLinks() to IntegrityQueryPostgres that combines detection
and fix into a single UPDATE ... WHERE __id IN (SELECT ...) statement.
Detection and fix execute under the same MVCC snapshot, eliminating the
application-level gap entirely.

The service (LinkFieldIntegrityService.checkAndFix) tries the atomic
method first. If the database engine doesn't support it (e.g., SQLite),
it falls back to the existing two-step approach. This is a safe,
backwards-compatible change — SQLite behavior is completely unchanged.

## What the /link-fix endpoint covers

For context, the endpoint handles 10 integrity issue types. This PR
improves only InvalidLinkReference. Here is the full list:

| Issue Type | What it detects | Fix applied |
|---|---|---|
| InvalidLinkReference | JSONB link column diverged from junction/FK source of truth | Rebuilds JSONB from junction/FK data (THIS PR) |
| MissingRecordReference | Junction table has rows pointing to deleted records | Deletes orphaned junction rows |
| ForeignTableNotFound | Link field references a deleted table | No auto-fix (requires manual intervention) |
| ForeignKeyHostTableNotFound | Junction table is missing | No auto-fix |
| ForeignKeyNotFound | Missing FK columns in junction table | Recreates columns, backfills from JSONB |
| SelfKeyNotFound | Missing self-reference key in junction | No auto-fix |
| SymmetricFieldNotFound | Bidirectional link missing its counterpart | Converts to one-way link |
| ReferenceFieldNotFound | Referenced record was deleted | Deletes orphaned reference |
| UniqueIndexNotFound | Missing unique constraint for OneOne links | Creates the index |
| EmptyString | Text fields have empty strings instead of NULL | Converts to NULL |

## Relationship types handled

The atomic fix handles all four relationship types:
- ManyMany (isMultiValue=true): Rebuilds JSONB array from junction table
- OneMany (isMultiValue=true): Same as ManyMany
- ManyOne (isMultiValue=false, FK in same table): Rebuilds single JSONB object from FK column
- OneOne (isMultiValue=false, FK in host table): Rebuilds via cross-table join

## Files changed

- abstract.ts: Added atomicFixLinks() with default null return
- integrity-query.postgres.ts: PostgreSQL implementation of atomicFixLinks()
- link-field.service.ts: checkAndFix() tries atomic first, falls back to two-step
