fix(palette): give the "edit" badge a chord that can actually fire

Every row with an edit variant — quick-connect and every saved SSH profile
— advertised "→ edit", and neither of the two gestures behind it worked:

- `→` never reaches the palette. gpui-component's `Input` binds bare
  `right` to MoveRight inside its own key context, and the query field has
  focus the whole time the palette is open, so the keystroke is consumed
  before the scrim's handler sees it.
- `⌘↵` never reaches it either. The app binds `secondary-enter` to
  ToggleFullscreen, which matches first — pressing it in the palette put
  the window into fullscreen.

So a saved profile could not be opened for editing from the palette at
all, which is the only row-scoped way in; Settings → SSH lists them, but
loses which row you were on.

The chord is now `secondary-e`, claimed by neither the input nor the app.
It lives in one `EDIT_GESTURE` constant next to the matcher that reads it,
and the badge renders through `key_tokens`, so it says ⌘E on macOS and
Ctrl E elsewhere rather than a hardcoded arrow baked into three locale
tables. `EditHint` is now just the word ("edit" / "编辑" / "編集").

Verified on screen: the badge reads "edit ⌘E", and ⌘E on a quick-connect
row opens the SSH profile form with the host, user and port already filled
in from the query.
