## Summary
- Adds a new admin-only **Security** tab to the Admin Panel (alongside
General/Apps/AI/Config/Health) containing a **Signing Keys** section.
The tab is intentionally introduced now so the upcoming **Encryption
rotation** work can land as a sibling section.
- Lists every JWT signing key with key id, `createdAt`, `revokedAt`,
current/active/revoked status, and a **7-day verification count** read
from Redis. A trailing row aggregates **legacy HS256** verifications so
it is clear when the deprecated path is still in use.
- Lets an admin **revoke** a public key. Revoking the current key drops
`isCurrent`, sets `revokedAt`, nulls the encrypted `privateKey` and
clears the in-process cached current key; the existing lazy path in
`JwtKeyManagerService.getCurrentSigningKey()` then mints a fresh current
key on the next sign.
## Backend
- `SigningKeyVerifyCounterService` — bucketed Redis counter under the
existing `EngineMetrics` namespace. 1-day UTC-aligned buckets, 8-day TTL
refreshed on every increment, batched read via `mget`. Failures are
swallowed and logged at `warn` so a Redis hiccup cannot break auth.
- `JwtWrapperService.verifyJwtToken` records verifies **after success**
for both ES256 (`kid` as identifier) and HS256 (the literal `legacy`
identifier).
- `JwtKeyManagerService.listSigningKeys()` and `revokeSigningKey(id)`:
list ordered by `isCurrent DESC, createdAt DESC`; revoke is idempotent,
validates the UUID, invalidates the public-key cache, and resets the
cached current-key promise.
- `AdminPanelResolver.getSigningKeys` (query) and `revokeSigningKey`
(mutation) are both decorated with `@UseGuards(AdminPanelGuard)` so they
are admin-only, like the 35 existing admin-only methods on this
resolver. `privateKey` is never returned over GraphQL.
## Frontend
- New `SECURITY` tab id wired into `SettingsAdminContent` and
`SettingsAdminTabContent` (gated by `canAccessFullAdminPanel`).
- `SettingsAdminSecurity` / `SettingsAdminSigningKeysTable` strictly
reuse existing admin-panel components: `Section`, `H2Title`,
`Table`/`TableRow`/`TableCell`/`TableHeader` from `@/ui/layout/table`,
`Tag`/`Button` from `twenty-ui`, and `ConfirmationModal` mirroring the
queue retry/delete modals. Only one minimal styled helper for the
monospaced UUID rendering.
- `useRevokeSigningKey` uses `useApolloAdminClient`, refetches
`GetSigningKeys`, shows success/error snackbars (same pattern as
`useRetryJobs`/`useDeleteJobs`).
