Legal + release-readiness pass for Hash Bags launch

Legal (aligned with the hosted hash.boats Terms & Privacy):
- Rewrite in-app Terms (assets/text/Terms_of_Use.txt): drop the false 'No Fiat
  Operations'/'No Embedded Applications' clauses; add MoonPay (optional, where
  available), Trocador swaps + ~1% fee disclosure, WalletConnect, sanctions/18+,
  Apple EULA rider, and PA + class/jury-waiver dispute terms.
- Reconcile PRIVACY.md with the canonical hosted policy.
- Add THIRD_PARTY_LICENSES.md; correct the blanket 'MIT' claim in README (app
  code MIT; bundles BSD-3/Apache-2.0/LGPL-3.0); fix README build-doc + LICENSE.md
  links and copyright year.
- Standardize in-app legal naming to 'Terms of Service'; add in-app links to
  hash.boats/terms and /privacy.

Release fixes:
- Align URL scheme hashwallet:// -> hashbags:// (matches registered scheme) so
  WalletConnect/Trezor/quick-action deep links work.
- Store-review gating: hide Buy action until a provider is available; hide the
  empty 'Apps' tab.
- Exclude removed chains (SOL/TRX/ZEC/DCR/ZANO + tokens) from swap pickers.
- Residual Cake branding: macOS CFBundleDisplayName and Windows Runner.rc
  (Hash Wallet -> Hash Bags); remove Android cakewallet://y.at leftover.
- Genericize internal-infra comments in CI workflows.
