Fix wallet pill filters and drag-and-drop for multi-chain wallets

- Fix ReferenceError: _dragAddr → _dragKey in pill checkbox onchange handler,
  restoring the ability to toggle wallet filters in the nav-bar
- Replace toggleWalletPill with setWalletChecked(key, this.checked) so pill
  checkboxes directly update filter state, sync all checkboxes, and refresh
  charts (matching the ledger-header checkbox behavior)
- Drag-and-drop reorder: switch from plain addresses to compound keys
  ("addr:chain") in dropWalletReorder and setWalletOrder, fixing clones
  when dragging wallets that share an address on different chains
- Update inline fallback WalletManager with the same compound-key logic
