Rebrand: 'Hash Wallet' → 'Hash Bags' (visible name only)

Avoids any confusion / potential trademark friction with HashWallet
(Spanish hardware-wallet company). Hash Bags is a more distinctive
name, harder to collide with, and we can still rank for 'hash wallet'
search via App Store / Play Store subtitle ('Hash Bags - A Wallet
for your Coins').

What changed (all user-visible strings):
- Launcher labels: android/app.properties, scripts/android/app_env.sh,
  scripts/ios/app_env.sh, linux window title (CMakeLists +
  my_application.cc)
- In-app text: lib/generated/i18n.dart + ARB sources under res/values/
- Brand docs: README.md, CONTRIBUTING.md, PRIVACY.md,
  assets/text/Terms_of_Use.txt, assets/text/Release_Notes.txt
- hash.boats website: index.html, og-image.svg + regen og-image.png,
  site.webmanifest, styles.css comment, splash/confirm/pulse/mark/
  lockup svg titles, report/index.html, server/server.js
- CI workflow display names ("Hash Bags Linux build", etc.)

What did NOT change (deliberate):
- Bundle ID / Package: com.suchsoftware.hashwallet (immutable app
  identity on App Store + Play Store — changing == orphaning the app)
- Binary name: hash_wallet (Linux executable)
- Dart import paths: package:hash_wallet/...
- Git repo: hash-wallet (Such-Software/hash-wallet)
- URL scheme: hashwallet:// (internal deep links)
- support@such.software (no domain change yet)
- App Store / Play Store listing names (whatever was registered there
  stays; we updated launcher label only)
- hash.boats domain (still the wallet site)

Also kept the '#ash Wallet' wordplay in the nav but updated to
'#ash Bags' so the # mark still serves as the H. Nav reads:
[# mark] #ash Bags

Website hero tagline now matches the App Store sub-title concept:
'A wallet for your coins. Open-source, non-custodial, multi-chain.
Privacy-leaning by default.'
