fix(maintainerr): inject ingress base path into UI files for React Router

Browse Source 
The upstream Maintainerr builds its Vite/React frontend with a
__PATH_PREFIX__ placeholder that gets replaced at runtime by start.sh
using the BASE_PATH env var. This sets:
- React Router's basename (createBrowserRouter)
- API base URL (axios calls)
- EventSource URLs
- Vite asset prefix

Without this replacement, React Router has an empty basename and can't
match the ingress URL (/api/hassio_ingress/<token>/), returning
"No route matches URL".

Fix: Replace __PATH_PREFIX__ in the built UI files with the HA ingress
entry before starting the app. Remove nginx sub_filters (no longer
needed since the UI files already reference the correct ingress-prefixed
URLs). Keep the nginx rewrite rule to strip the prefix on the server side.

# ─── Inject ingress base path into the built UI files ─────────────────────────
# The upstream Maintainerr Vite build embeds /__PATH_PREFIX__ as a placeholder
# for the base URL. The upstream start.sh replaces it with $BASE_PATH at runtime.
# For HA ingress, the base path is the dynamic ingress entry (e.g.
# /api/hassio_ingress/<token>). We perform the replacement here so the React
# Router basename and all asset/API URLs point through the ingress path.
# We intentionally do NOT export BASE_PATH so that the NestJS server keeps its
# routes at the root — nginx's rewrite rule strips the ingress prefix on the
# server side.
