feat: add Settings live stream analysis button and diagnose Laya batch failure (#14)

Browse Source 
Add a Settings action to manually rerun Live TV stream analysis:
it triggers an admin-guarded projection rebuild endpoint that
groups streams into logical channels (covering channels present
before the projection existed) and reruns language/Laya detection,
with progress presented via liveAnalysisPresentation. Harden the
Laya batch path that failed with 'Local AI language matching
failed' by surfacing the underlying cause and falling back to
standard matching cleanly. Guard admin-only rebuild through a new
authz helper and cover routes, service and presentation with tests.
