   Backports:

   • #34370
   • #34671

   And the rc2 release process things

2. Wallet/bdb: Safely and correctly list files only used by the single wallet

   If any other files exist in the directory, we cannot assume the sharable files are exclusively for this wallet.
   But if they are, this also cleans up other log.* files

3. Wallet/Migration: If loading the new watchonly or solvables wallet fails, log the correct wallet name in error message

   Github-Pull: #34370
   Rebased-From: 60f529027c6eacbdc298fab50192f8c60d7082a1

4. Wallet/Migration: Skip moving the backup file back and forth for no reason

   Since we no longer delete the wallet directory, there's no need to vacate it
   The moving only served to risk errors by crossing filesystem boundaries (which fs::rename can't handle)

5. Bugfix: Wallet/Migration: Move backup into wallet directory when migrating from non-directory

   While 30.x+ keep backup files in walletdir, 29.x places them in the migrated wallet directory

6. QA: tool_wallet: Check that db.log is deleted with a lone legacy wallet, but not with a shared db environment

   Github-Pull: #34370

    ACK bfaec08634ba4fe7f466070aab83fb33f7f5fc5e

    These all look good to me. Only conflict looks like the MigrateLegacyToDescriptor signature.

    Release notes look good too. Can re-review if you add 34671

17. doc: Update Guix install for Debian/Ubuntu
