chore: merge from develop to preview

[jorbuedo]

Note

Switch voting registration to hex metadata with better fee estimation, add legacy public key QR parsing, batch/simplify airdrop thaw notifications, and refine airdrop/address UX and icons.

• Transaction/Voting (CIP-15/36):
  • Use hex for voting/staking keys and addresses in metadata; update creators createCIP15VotingMetadata and createCIP36VotingMetadata (+ tests).
  • Adjust fee/size estimates and buffers; in builder, precompute size (incl. metadata/witness set) to set manual fee before addChangeIfNeeded.
  • Voting recipe updated to hex conversions, larger CIP-36 size/buffer, and nonce/TTL handling unchanged.
• Airdrop:
  • Schedule one notification per unique thaw date; prefetch existing IDs; simpler content; Android channel setup; robust errors.
  • Eligibility fetch: disable retries, add small rate-limit delays, include external addresses, and stable ordering; expose hard refresh.
  • Manual Address modal: multiline input to process multiple addresses with caching, rate-limit delays, results summary, and query invalidation; removal updates React Query cache directly.
• Wallet Manager:
  • For read-only xpub wallets, store initial address with enableDiscovery: false.
• Links/Scan:
  • Add parseLegacyPublicKeyQR to support legacy JSON {publicKeyHex,path}; integrate into scanner before Cardano link parsing.
• UI/Icon:
  • Map STAKE_DEREGISTRATION to Staking icon instead of StakingKeyDeregistered.
