[viewer] Surface recovered TOC names in the PAK browser + refresh RE panel

- Move the IDXD->TOC-path resolver into sylpheed-formats as
  IdxdObject::recover_toc_path() so the CLI `pak list` and the GUI pack
  browser share one implementation (behaviour-preserving; CLI still
  resolves 308/1004 on GP_MAIN_GAME_E).
- PAK browser now shows each entry's recovered original path (via the
  name-hash) in green, in both the entry list and the IDXD detail heading.
- Replace the stale welcome "RE Notes" table (mesh/audio "unknown") with an
  accurate reverse-engineered-formats status grid + correct authorship.
