v5.0.2: hide hardware-restore option + version bump

- wizard: hide the hardware-device wallet option (wownero has no Ledger/Trezor
  support; inherited Feather cruft).
- bump version 5.0.1 -> 5.0.2.

v5.0.2 also rebuilds the Linux AppImage in an ubuntu:24.04 container (glibc 2.39)
so it runs on Ubuntu 24.04 / Mint / Debian — v5.0.1's AppImage was built on
glibc 2.43 and would not start elsewhere. No wallet-code change: wallets created
on pre-table-fix builds carry a stale restore height (blank balance); the fix is
to re-restore from seed.
