fix: wownero P0s, fail-closed RNG, iOS scheme, dep pins

- resetToDefault omitted Wownero: the reset button null-crashed and left
  WOW wallets with an empty node list
- accountLabel was missing a return and rendered blank for WOW wallets
- sec_random now throws instead of returning empty bytes when the native
  entropy channel fails or under-delivers
- iOS builds no longer register the leftover cakewallet:// URL scheme
- WOW fee estimate now fetched from the connected daemon's
  get_fee_estimate RPC and cached; the inherited XMR constant table
  remains only as a pre-fetch fallback
- pin cake_backup, flutter_local_authentication, and bech32 git deps to
  their locked SHAs for reproducible builds
