fix: use lossless-capable TIDAL client for normal streamingHEADmaster

The default tidalapi OAuth client no longer has lossless/hi-res streaming
entitlements, causing all downloads to fall back to AAC 320 kbps even when
HI_RES_LOSSLESS is requested.

- Replace broken Atmos/Fire TV client credentials with the working Android
  Atmos client (km8T1xS355y7dd3H) which supports lossless stereo as well as
  Dolby Atmos.
- Use that client for the main session, not just Atmos tracks.
- Refresh existing tokens on login so they are bound to the new client.
