feat(wallets): open external wallets in place via datadir link (no copy)

Browse Source 
Replace the "Import" action — which copied an out-of-datadir wallet into the
datadir and cluttered the list with hard-to-tell-apart duplicates — with an
in-place "Open" that links the real file into the datadir under a stable
per-target name (wallet-ip-<FNV8>.dat) and switches to it. The daemon only
loads a bare filename from its own datadir, so a link is the minimal bridge:
hard link first (no privileges, same volume — covers non-admin Windows),
symlink fallback (cross-volume), then an error. Never a copy (that would fork
the wallet) and never a delete of a real file.

Also:
- show each external wallet's originating sub-directory (…/Backups/2021)
- add a per-row "open folder location" button
- widen the modal (780 → 860) for the extra button
- guard the daemon against a dangling link (external file moved / USB
  unplugged) by falling back to wallet.dat rather than creating an empty one

Per-target link names (not one shared name) make switching between two
external wallets a real -wallet switch, so the rescan/cache index tracks each
correctly. Drops the now-dead wallets_import* i18n keys and back-fills the new
open/folder strings across all 8 languages + rebuilds the CJK subset.
