Atomic Swaps: master tracking issue

[Maxnflaxl]

Master tracking issue for open Atomic Swap work in the core wallet.

Regression: swap offers rejected as foreign (breaks UI offer board)

Since d4d0e78 ("wallet: AtomicSwapTransaction - using nonce addresses", shipped with 7.3) FillSwapTxParams() allocates a bare key id via AllocateKidRange(1) and no longer persists a WalletAddress. SwapOffersBoard::publishOffer() only recognizes publishers found in IWalletDB::getAddresses(true), so every newly created offer throws ForeignOfferException ("Offer has foreign Pk and will not be published"). User reports: BeamMW/beam-ui#1017, BeamMW/beam-ui#1073. A fix (create and persist the publisher address in FillSwapTxParams(), as the v6 API's createWID() did before the change) is being prepared.

Follow-up to the fix: define the publisher-address lifecycle (expire vs. delete on offer expiration/cancel/accept). The address must stay resolvable while SwapOffersBoard may still re-broadcast the offer status (sendUpdateToNetwork()/isOwnOffer() look it up in the own-address set), i.e. roughly for the BBS message lifetime after the offer reaches a terminal state.

Sub-issues

• Add text in transaction details (atomic swap) #1103 — Add text in transaction details (auto-unlock notice while swap is in progress)
• In CLI wallet, can create swap that exceeds the balance for ether #1697 — CLI wallet allows creating a swap that exceeds the balance for ether/usdt/wbtc/dai
• Validator works wrong If user has many coins and swap feerate can be not enough for swap #1039 — Fee-rate validator ignores input count; swap fee rate can be insufficient with many small coins

UI-side issues are tracked in BeamMW/beam-ui#1267.
