Implements AUDIT_REPORT.md M-7 and L-10:
- M-7: new CI job 'db-tests' runs Category=LiveDb tests against a pgvector/pg16
service container — permanent regression coverage for the search paths the
InMemory provider can't translate (ts_rank_cd weighting, ts_headline sentinels,
pg_trgm typo fallback, pgvector cosine ordering). Previously these were only
verified manually. Tests soft-skip when LIVEDB_CONNECTION is unset, so local and
existing CI runs are unaffected. Verified green against a real pgvector container.
- L-10: 'format' CI job (dotnet format --verify-no-changes) so --no-verify pushes
can't bypass the formatting gate.
- frontend job: node 20 -> 22 (aligns with the vite 8 upgrade).
Full suite: 54/54 (51 + 3 LiveDb when live).

Phase 5 re-validation caught a functional regression: the V-10 clamp in
SearchService.SearchAsync also capped CleanupService's internal target resolution
(pageSize 10000 -> 200), silently limiting bulk cleanup-by-query to 200 emails.
The clamp belongs at the user-facing trust boundary, not the shared service: move
MaxPageSize (200) enforcement into SearchController (both the POST body and GET query
paths). Internal callers of ISearchService now request large pages unhindered, while
user requests are still bounded. Adds a regression test proving SearchService returns
a 250-row page uncapped. No security regressions per Phase 5. All 39 tests green.

Defense-in-depth tenant isolation: every user-owned entity (Email, Sender,
MailThread, MailDomain, Attachment, Label, SyncState, AnalyticsAggregate,
WidgetLayout, UnsubscribeItem) gets a global query filter restricting reads to the
authenticated user. AppDbContext takes an optional ICurrentUser; CurrentUserId is
Guid.Empty for background workers / design-time, which DISABLES the filter so sync
and tooling (which already scope by an explicit userId) are unaffected. On the HTTP
attack surface a forgotten manual `WHERE UserId ==` can no longer leak another
tenant's rows.
Phase 1 confirmed no active IDOR; this is preventive, and prioritised now because the
upcoming automation engine will add many new queries.
Also: moved the Npgsql-only tsvector FTS mapping out of EmailConfiguration into
AppDbContext.OnModelCreating, guarded by Database.IsRelational() (Ignored otherwise),
so non-relational test providers work — honouring the existing Email.SearchVector
comment. Production (Npgsql) model is unchanged; no migration needed.
Adds 3 cross-user tenant-isolation integration tests. All 38 tests green.
