fix(dashboard): log clearly when the built frontend is missing

Browse source 
Previously, if meshai/dashboard/static/ (or its index.html) was absent,
create_app() silently skipped mounting /assets and registering the
root/catch-all routes -- no log, no error. Any request to "/" would
just 404 with FastAPI's generic "Not Found", giving no clue why.

This was latent before (Docker always builds the frontend, and a git
checkout with the artifacts committed always had the directory), but
now that static/ is untracked, a fresh pip install without the frontend
build step will hit this path as its first real-world trigger. Add a
warning log naming the missing path and the exact build command, and
make clear the bot/API are unaffected -- only the dashboard UI is
absent.
