feat(viewer): data pack (.pak / IDXD) browser

Browse Source 
Roadmap #3. The explorer can now open IPFB data packs — the game's ship/weapon/
mission definition tables. Selecting a `.pak` shows a master-detail browser:
entry list (hash · inner-format · identity) on the left, the selected IDXD
object's schema + explicit-field property table on the right.

Load path: a `.pak` selection reads the index plus its sibling `.pNN` segments
(ISO reader or extracted dir, probing p00.. until the first gap), assembles via
PakArchive::from_parts, and builds owned PakRow/PakDetail entirely off-thread —
so the UI holds only plain data (no borrow of a PakArchive, WASM-safe). Two
decode caps (64 MiB cumulative, 16 MiB/entry) keep a huge sound.pak from hanging;
over-budget entries show as "(not decoded)".

Wiring mirrors the texture path: new IsoLoaderMsg::PakLoaded → PendingPak staging
→ apply_pak. A shared reset (free GPU handle + clear texture/text/pak previews)
runs in both apply systems, so exactly one viewer is active per selection and the
prior GPU texture is always freed when switching modes.

Reuse over duplication: the CLI's inner_label / idxd_identity move into the
formats crate as pak::inner_format_label and IdxdObject::identity (bodies
verbatim → CLI output unchanged), now shared by CLI and GUI.

PakView registered unconditionally (wasm-safe; population native-only). ViewMode
unchanged — the central panel dispatches on the populated resource. Workspace
builds; 22 formats tests + all crate tests pass.
