feat: mcpctl mcptoken verbs + mcpd auth dispatch + audit plumbing

Adds the end-to-end CLI surface for McpTokens and the mcpd auth dispatch
that recognizes them.

mcpd auth middleware:
  - Dispatch on the `mcpctl_pat_` bearer prefix. McpToken bearers resolve
    through a new `findMcpToken(hash)` dep, populating `request.mcpToken`
    and `request.userId = ownerId`. Everything else follows the existing
    session path.
  - Returns 401 for revoked / expired / unknown tokens.
  - Global RBAC hook now threads `mcpTokenSha` into `canAccess` /
    `canRunOperation` / `getAllowedScope`, and enforces a hard
    project-scope check: a McpToken principal can only hit
    `/api/v1/projects/<its-project>/...`.

CLI verbs:
  - `mcpctl create mcptoken <name> -p <proj> [--rbac empty|clone]
    [--bind role:view,resource:servers] [--ttl 30d|never|ISO]
    [--description ...] [--force]` — returns the raw token once.
  - `mcpctl get mcptokens [-p <proj>]` — table with
    NAME/PROJECT/PREFIX/CREATED/LAST USED/EXPIRES/STATUS.
  - `mcpctl get mcptoken <name> -p <proj>` and
    `mcpctl describe mcptoken <name> -p <proj>` — describe surfaces the
    auto-created RBAC bindings.
  - `mcpctl delete mcptoken <name> -p <proj>`.
  - `apply -f` support with `kind: mcptoken`. Tokens are immutable, so
    apply creates if missing and skips if the name is already active.

Audit plumbing:
  - `AuditEvent` / collector now carry optional `tokenName` / `tokenSha`.
    `setSessionMcpToken` sits alongside `setSessionUserName`; both feed a
    per-session principal map used at emit time.
  - `AuditEventService` query accepts `tokenName` / `tokenSha` filters.
  - Console `AuditEvent` type carries the new fields so a follow-up can
    add a TOKEN column.
