feat(v1.1.7-secrets): secrets SDK + table + admin API + dashboard

Encrypted per-app secrets, reachable from scripts as
secrets::{get,set,delete,list}(name) and managed from the dashboard
Secrets tab. Values are AES-256-GCM-sealed with the process master key
(picloud_shared::crypto) before they touch Postgres; the repo only ever
sees ciphertext + nonce. JSON round-trip preserves Rhai types.

- migration 0023_secrets.sql (PRIMARY KEY (app_id, name)).
- SecretsService trait (picloud-shared) + SecretsServiceImpl + repo
  (manager-core), wired into the Services bundle and Rhai engine.
- Capability::AppSecretsRead/Write (→ script:read / script:write); no
  new Scope variants (seven-scope commitment).
- Admin API GET/POST/DELETE /apps/{id}/secrets (list returns names +
  updated_at, never values).
- build_app now takes a MasterKey, sourced from PICLOUD_SECRET_KEY in
  main.rs; test callers pass a fixed test key.
- 64 KB value cap (PICLOUD_SECRET_MAX_VALUE_BYTES); no ServiceEvent
  emission (secret writes don't fire triggers, by design).

+//!
+//! ```rhai
+//! secrets::set("stripe_key", "sk_live_xxx");
+//! secrets::set("oauth", #{ client_id: "abc", client_secret: "xyz" });
+//! let key = secrets::get("stripe_key");          // value or ()

+//! let page = secrets::list(#{ cursor: (), limit: 100 });
+//! //   page = #{ names: [...], next_cursor: () | "..." }
+//! ```
+//!
+//! Collection-less (secrets are per-app, like pubsub topics) so there's
+//! no `::collection(...)`. Values are any JSON-serializable Rhai value
+//! (String/Map/Array/number/bool); a String round-trips back as a
+//! String. `app_id` is derived from `cx.app_id` in the service — it
+//! never appears in the script-side signature, preserving cross-app
+//! isolation.

+//! `SecretsServiceImpl` — wires the `SecretsRepo` underneath the
+//! `picloud_shared::SecretsService` trait that scripts see via the Rhai
+//! bridge.
+//!
+//! Layers added here (vs the raw repo):
+//!
+//! 1. Name validation (non-empty, ≤255 bytes) at the SDK boundary.
+//! 2. **Script-as-gate authz**: when `cx.principal.is_some()` we run
+//!    `authz::require(...)`; when it's `None` (public unauthenticated
+//!    HTTP) we skip the check. Cross-app isolation is unaffected — every
+//!    query is keyed by `cx.app_id`, never an argument.
+//! 3. **JSON ⇄ ciphertext**: `set` serializes the value to JSON bytes,
+//!    enforces the per-secret size cap, and AES-256-GCM-seals it; `get`
+//!    decrypts and deserializes back to the same JSON shape (a String
+//!    round-trips to a String, not a JSON-quoted `"\"…\""`).
+//!
+//! Deliberately **no `ServiceEvent` emission** — secret writes do not
+//! fire triggers (footgun avoidance; see `docs/sdk-shape.md` + the
+//! v1.1.7 brief §2).
