Frontend (Unit 2 completion): dual dev-server tooling (pnpm dev:slave,
pnpm dev:all), per-instance browser tab titles, and a backend
capability check (SystemController + useSystemCapabilities +
ModuleGuard) so a Master-only page is hidden on a slave instance
instead of assuming every backend has every module.
Master/slave protocol fixes surfaced by actually running master and
slave side by side locally:
- Deactivating a CMS instance (Inactive) now releases the slave's
master gate instead of leaving it stuck on its last pushed status.
- The periodic integrity check now also re-pushes status to every
reachable slave (previously URL-verification only) and runs once
immediately on startup.
- Added the originally-specified (but never implemented) slave-pull
path: a slave now periodically polls its own status from the master
(GET /api/v1/SlaveStatus) and fails open to Available if the master
is unreachable for too long, complementing the existing push.
- The slave's own Settings page can no longer "successfully" change
local availability while the master controls it; it's now locked
with an explanatory banner and the backend rejects the write with
409 instead of silently no-op'ing it.
- CMS instance status badges now match the dashboard's color/icon
styling instead of a plain grey badge.
Also corrected the master-cms-module design docs to match this
as-built behavior, and flagged (without a full rewrite) a larger,
pre-existing divergence between its inception-stage application
design and what construction actually built.

Finishes the master-cms-module feature (Units 1-4): runs Build and
Test across master-backend, slave-availability-extension and
frontend-cms-page, fixes a missing Availability EF migration for
MasterRegistration and a TanStack Query v5 mutation-callback type
break, adds the missing MasterModule appsettings section, and
documents the module in README.md. Also seeds a tech-debt-backlog
feature to track dead config and pre-existing/introduced frontend
lint findings for later cleanup.
