add workaround for jpackage issue where mime-info is not generated on linux
What changed, and why it matters
This commit adds a build-system workaround so that Linux installers for the Sparrow Wallet correctly register file types (like .psbt Bitcoin transaction files) and URI handlers (like bitcoin: payment links) with the desktop environment. It is a packaging fix, not a code change that affects wallet security or user funds.
No security action required; treat as a normal build/packaging improvement.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch registers a new Gradle copy task, copyMimeInfo, that runs during jpackage builds on non-headless Linux and places sparrowwallet-Sparrow-MimeInfo.xml into the jpackage output lib directory. The XML file declares MIME types for .psbt, .txn, and .asc files plus x-scheme-handler entries for bitcoin, auth47, and lightning URIs. This compensates for a jpackage bug where mime-info is not generated automatically on Linux.
