feat(bridge): allow slug -> table_id resolution via BASEROW_TABLE_IDS — Patch 029

Callers can now hit /api/v1/views/table/personne instead of /table/609
and the bridge resolves the slug to the numeric Baserow table ID using
the BASEROW_TABLE_IDS env var (already present, just unused before).

Resolution accepts either a digits-only string (preserved behavior) or
a slug. Falls back to a 400 validation error when neither matches.

Note: this fixes the *routing* layer only. The downstream Baserow API
still requires a user JWT for some operations (notably GET /views/table)
and returns 401 PERMISSION_DENIED with the current DB-token-based bridge
config. That's a separate architectural concern — tracked for a later
patch (bridge user-JWT exchange).

Patch 029.
