feat: add ordinal spend warning to confirm transaction view
What changed, and why it matters
This commit adds a warning message shown to users when they are about to spend a Bitcoin UTXO that contains an ordinal inscription. It is a user-interface safety feature, not a fix for a code vulnerability. It helps prevent users from accidentally spending or losing valuable or meaningful inscription assets.
No security action required. Treat as a normal feature addition. Optionally review whether the ordinal lookup correctly handles all input types and whether the warning should block confirmation rather than just inform.
Security signals we found
User-facing safety warning for accidental asset loss
No changes to cryptographic, signing, or network code
No input validation or access-control changes
No bug fix or vulnerability remediation evident in diff
Evidence from the diff
The change introduces a new Builder widget in the transaction confirmation view. Before confirming a send, it checks each selected UTXO against the local Isar database’s ordinals collection. If any input matches a known ordinal by walletId, txid, and vout, a warning banner is displayed. The commit only adds UI logic and database reads; it does not modify transaction construction, signing, or validation.
