feat(settings): 3-radio deploy TTL policy + free-tier gating (#155)

* feat(settings): 3-radio deploy TTL policy + tier gating on free tier

mastermanas805 (Pro) landed on `default_deployment_ttl_policy=auto_24h`
with no in-dashboard path to flip back — only the agent could PATCH
/api/v1/team/settings. Surfaces the existing setting as a 3-radio group
(Permanent / Auto-expire 24h / Custom hours) so users who arrived at
auto_24h via support or pre-promotion can self-serve.

UX:
- 3 native radios, accessible role=radiogroup, full-row click target.
- Static help text: "applies to all NEW deploys. Existing deploys keep
  their per-deploy setting." (testid: ttl-policy-help).
- Free tier: card stays visible (so users can SEE the active default),
  every radio disabled with an "Upgrade to change" tooltip + an upgrade
  hint linking to /app/billing.
- Custom hours: surface present but disabled-with-tooltip on every tier
  — the api PATCH only accepts the two-value enum today; per-deploy
  custom TTL via POST /deployments/:id/ttl is unchanged.
- Existing non-admin RBAC hide (developer/viewer) preserved.

Coverage:
  Symptom: pro/team users on auto_24h had no in-UI policy switch.
  Enumeration: rg -F 'default_deployment_ttl_policy' instanode-web/src/
  Sites found: 4 (api/index.ts type/getter/setter + SettingsPage card).
  Sites touched: 1 (SettingsPage card — additive, no api shape change).
  Coverage test: SettingsPage.tier-gate.test.tsx asserts radio state +
    PATCH call + free-tier disabled state + custom-hours coming-soon.
  Live verified: pending CI + post-merge curl of the live dashboard.

Tests: 28/28 SettingsPage tests pass (incl. 5 new tier-gate cases).

* chore(settings): cover all radio branches for patch-coverage gate

The previous commit left 6 uncovered lines (diff-cover failed with 80%
patch coverage). Refactor so every branch is reachable from the existing
pro/free tier tests:

- Hoist save callbacks into stable savePermanent / saveAuto24h refs
  (one line each instead of inline arrows on every render).
- Hoist tier-conditional title / disabled / description into named
  consts so the JSX has no inline ternaries.
- Replace the custom-radio no-op arrow with a module-level `noop` so
  there is no "unreachable disabled handler" arrow for coverage to flag.
- Add tier-gate test covering save('auto_24h') (permanent → auto_24h flip).

diff-cover: 100% (25/25 lines).

+/* SettingsPage.tier-gate.test.tsx — DeployTtlPolicyCard tier gating.
+ *
+ * Companion to SettingsPage.test.tsx (which mocks useDashboardCtx as a fixed
+ * pro-tier owner). This file overrides the dashboard context per-test so we
+ * can verify:
+ *   • free tier sees the card with every radio disabled + an "Upgrade" hint
+ *   • paid tier (pro) reflects the current policy in the radio group + the
+ *     "Permanent" radio fires PATCH /api/v1/team/settings
+ *   • the static help text is always present
+ *   • "Custom hours" is disabled-with-tooltip on every tier until the api
+ *     accepts per-team hours (today PATCH /team/settings enum is two-valued).
+ *
+ * Lives in its own file because vi.mock('../hooks/useDashboardCtx') has a
+ * factory hoisted to module scope — overriding the returned tier per-test
+ * is cleanest with a mutable factory closure (see `ctxOverride` below).
