fix(seerr): add trailing slash to ingress root-link rewrites (#2976)

Seerr's Discover link is href="/". nginx rewrote it to the bare ingress
entry, but Home Assistant only routes ingress on
"/api/hassio_ingress/{token}/{path:.*}", so a URL without the trailing
slash matches no route and Home Assistant answers its own plain-text
"404: Not Found" before the request reaches the add-on.

Closes #2975

+- Fixed `404: Not Found` when clicking **Discover** in the sidebar through ingress (#2975). Seerr's Discover link points at `/`, which nginx rewrote to the ingress entry without a trailing slash; Home Assistant only routes ingress on `/api/hassio_ingress/<token>/…`, so the request was rejected by Home Assistant before reaching the add-on. Only ingress was affected; the directly published port 5055 always worked.
