Clean up wish temp playlists and show playback details

[TimUx]

Summary

• harden FPP status parsing and always clean up the temporary wish playlist so queued songs can play in sequence
• expose mode/playlist/sequence details through the state API and render them alongside the status on the home page
• adjust layout/styling for the status block to show the extra playback metadata

Testing

• python -m py_compile app.py

💡 Codex Review

https://github.com/TimUx/fpp-control/blob/4576f9b4d34176f9975d5dbe7340419646e39e23/app.py#L155-L160
Use media type for media‑only wish entries

Media-only wishes are written to the temporary playlist with type hardcoded to "sequence" even when no sequenceName is provided. When a song from the requests list contains only mediaName (no accompanying sequence), the generated playlist item advertises itself as a sequence with a null sequence name, which FPP will skip or fail to play. These requests will sit in the queue and never start despite being accepted by the API.
