fix(channels): propagate tenant context through all channel handlers (#1278)

Pairing requests and message handlers were silently using MasterTenantID
instead of the correct tenant because context.Context had no tenant set.

Root cause: instance_loader.go passed bare ctx (no tenant) to
startChannelWithTimeout; channel handlers also missing store.WithTenantID
at entry points.

Channels fixed:
- instance_loader.go: pass instCtx (with tenant) to startChannelWithTimeout
- Telegram, Bitrix24, Feishu: add store.WithTenantID at handler entry
- Facebook: add ctx param to handleMessagingEvent/handleCommentEvent + webhook_handler
- Pancake: add ctx param to handleMessagingEvent/handleCommentEvent + webhook_handler

Also fix consolidation pruner: PruneExpired SQL had tenant_id filter that
caused zero rows to ever be deleted (context had no tenant). Remove tenant
filter — pruning is a global maintenance operation.

Add regression tests:
- internal/channels/pancake/tenant_context_test.go (6 tests)
- internal/channels/facebook/tenant_context_test.go (4 tests)
- internal/consolidation/prune_expired_test.go (5 tests)

+// TestPruneExpired_* tests demonstrate the cross-tenant pruning bug that was
+// fixed in consolidation/workers.go.
+//
+// Bug: the periodic pruning goroutine in Register() called
+//
+//	deps.EpisodicStore.PruneExpired(context.Background())
+//
+// The OLD SQL implementation filtered by tenant_id = $1 using the tenant from
+// context. With context.Background() the tenant was uuid.Nil, so the SQL
+// evaluated tenant_id = '00000000-...' and matched NO rows in real tenants —
+// expired episodic summaries were never deleted.
+//
+// Fix: PruneExpired is implemented as a global maintenance operation that does
+// NOT filter by tenant_id. It deletes all expired rows across all tenants in a
+// single sweep. context.Background() is intentionally correct here.
+//
+// These tests validate:
+//  1. PruneExpired removes rows regardless of tenant scope.
+//  2. The pruning goroutine wired by Register() calls PruneExpired with a
+//     context that is NOT tenant-scoped (uuid.Nil) — confirming the fix.
+//  3. A mock that records calls can verify the cross-tenant contract.
