ObsidianDragon/src/ui/windows/wallets_dialog.h
DanS 06c8b99bce feat(wallets): in-app folder picker + roomier, full-width list controls 
Wallets dialog refinements:
- More space between wallet cards (cardGap: spacingSm -> spacingMd).
- "Scan another folder" is now always visible as a full-width button (no
  expandable toggle) that opens the new picker.
- The Create-wallet row and the scan button span the full list width, so their
  right edges align with the wallet cards / Open|Import buttons.

New in-app folder picker (folder_picker.h): a Material-styled modal replacing
the raw path input. Browse the filesystem (Up / Home / click a sub-folder),
see the *.dat wallet files present + a count, and pick a folder to scan. The
picker takes over the modal surface while open (the overlay framework doesn't
nest); it remembers the last browsed location across opens. Fixed-height card
(no auto-height feedback), UTF-8-aware truncation, full-node icons confirmed
in the embedded MaterialIcons range. Added a modal-folder-picker sweep surface;
verified at 100% + 150%, dark + light.
