feat(alerts): controller — DELETE/bulk-delete/bulk-ack/restore + acked/read filters + readAt on DTO

- GET /alerts gains tri-state acked + read query params
- new endpoints: DELETE /{id} (soft-delete), POST /bulk-delete, POST /bulk-ack, POST /{id}/restore
- requireLiveInstance 404s on soft-deleted rows; restore() reads the row regardless
- BulkReadRequest → BulkIdsRequest (shared body for bulk read/ack/delete)
- AlertDto gains readAt; deletedAt stays off the wire
- InAppInboxQuery.listInbox threads acked/read through to the repo (7-arg, no more null placeholders)
- SecurityConfig: new matchers for bulk-ack (VIEWER+), DELETE/bulk-delete/restore (OPERATOR+)
- AlertControllerIT: persistence assertions on /read + /bulk-read; full coverage for new endpoints
- InAppInboxQueryTest: updated to 7-arg listInbox signature

 - `AgentMetricsController` — GET `/api/v1/environments/{envSlug}/agents/{agentId}/metrics` (JVM/Camel metrics). Rejects cross-env agents (404) as defence-in-depth.
 - `DiagramRenderController` — GET `/api/v1/environments/{envSlug}/apps/{appSlug}/routes/{routeId}/diagram` (env-scoped lookup). Also GET `/api/v1/diagrams/{contentHash}/render` (flat — content hashes are globally unique).
 - `AlertRuleController` — `/api/v1/environments/{envSlug}/alerts/rules`. GET list / POST create / GET `{id}` / PUT `{id}` / DELETE `{id}` / POST `{id}/enable` / POST `{id}/disable` / POST `{id}/render-preview` / POST `{id}/test-evaluate`. OPERATOR+ for mutations, VIEWER+ for reads. CRITICAL: attribute keys in `ExchangeMatchCondition.filter.attributes` are validated at rule-save time against `^[a-zA-Z0-9._-]+$` — they are later inlined into ClickHouse SQL. `AgentLifecycleCondition` is allowlist-only — the `AgentLifecycleEventType` enum (REGISTERED / RE_REGISTERED / DEREGISTERED / WENT_STALE / WENT_DEAD / RECOVERED) plus the record compact ctor (non-empty `eventTypes`, `withinSeconds ≥ 1`) do the validation; custom agent-emitted event types are tracked in backlog issue #145. Webhook validation: verifies `outboundConnectionId` exists and `isAllowedInEnvironment`. Null notification templates default to `""` (NOT NULL constraint). Audit: `ALERT_RULE_CHANGE`.
-- `AlertController` — `/api/v1/environments/{envSlug}/alerts`. GET list (inbox filtered by userId/groupIds/roleNames via `InAppInboxQuery`; optional multi-value `state` + `severity` query params push filtering into PostgreSQL via `listForInbox` with `state::text = ANY(?)` / `severity::text = ANY(?)`) / GET `/unread-count` / GET `{id}` / POST `{id}/ack` / POST `{id}/read` / POST `/bulk-read`. VIEWER+ for all. Inbox SQL: `? = ANY(target_user_ids) OR target_group_ids && ? OR target_role_names && ?` — requires at least one matching target (no broadcast concept).
+- `AlertController` — `/api/v1/environments/{envSlug}/alerts`. GET list (inbox filtered by userId/groupIds/roleNames via `InAppInboxQuery`; optional multi-value `state`, `severity`, tri-state `acked`, tri-state `read` query params; soft-deleted rows always excluded) / GET `/unread-count` / GET `{id}` / POST `{id}/ack` / POST `{id}/read` / POST `/bulk-read` / POST `/bulk-ack` (VIEWER+) / DELETE `{id}` (OPERATOR+, soft-delete) / POST `/bulk-delete` (OPERATOR+) / POST `{id}/restore` (OPERATOR+, clears `deleted_at`). `requireLiveInstance` helper returns 404 on soft-deleted rows; `restore` explicitly fetches regardless of `deleted_at`. `BulkIdsRequest` is the shared body for bulk-read/ack/delete (`{ instanceIds }`). `AlertDto` includes `readAt`; `deletedAt` is intentionally NOT on the wire. Inbox SQL: `? = ANY(target_user_ids) OR target_group_ids && ? OR target_role_names && ?` — requires at least one matching target (no broadcast concept).
 - `AlertSilenceController` — `/api/v1/environments/{envSlug}/alerts/silences`. GET list / POST create / DELETE `{id}`. 422 if `endsAt <= startsAt`. OPERATOR+ for mutations, VIEWER+ for list. Audit: `ALERT_SILENCE_CHANGE`.
 - `AlertNotificationController` — Dual-path (no class-level prefix). GET `/api/v1/environments/{envSlug}/alerts/{alertId}/notifications` (VIEWER+); POST `/api/v1/alerts/notifications/{id}/retry` (OPERATOR+, flat — notification IDs globally unique). Retry resets attempts to 0 and sets `nextAttemptAt = now`.
