Run `prettier --write .` across all source files. Changes are purely
formatting: trailing commas, line wrapping at 120 chars, import
reordering, and CSS whitespace. No logic changes. Verified with
`prettier --check .` and `svelte-check` (0 errors, 0 warnings).
ADR-0021 pins the organization<->Feishu application binding to 1:1 and
the backend already exposes
GET /api/org/:orgSlug/feishu-application-connection
PUT /api/org/:orgSlug/feishu-application-connection (rotate/create)
DELETE /api/org/:orgSlug/feishu-application-connection (disable)
backed by FeishuApplicationConnectionService with versioned envelopes
(ADR-0024). The org-admin SPA had no surface for it, so the only
connection type the spec requires was unmanageable from the admin UI.
Add a Feishu page that reads the current connection (status, redacted
app fingerprint, active version, updatedAt), rotates credentials with
appId/appSecret/botOpenId (+ optional verificationToken/encryptKey) as
the backend requires, and disables with confirmation. Add the matching
api client (feishuApplication / rotateFeishuApplication /
disableFeishuApplication), a feishu nav icon and a nav entry.
