fix: rootless UID mapping corrections + credential injection

- Correct off-by-one in UID mapping: container UID N → host UID
  (100000 + N - 1), not (100000 + N)
- Deploy script auto-fixes UID ownership on every deploy
- Bitcoin UI nginx uses __BITCOIN_RPC_AUTH__ placeholder injected
  from secrets at deploy time
- container rules updated for rootless podman architecture
