fix(rtl): fix resize direction, path alignment, and i18n gaps

- Invert resize delta in RTL for drawer (useDrawerResize) and split panel (RightPanel)
- Add dir="ltr" to path/code value elements in instance-info panel
- Replace hardcoded English strings with i18n: Hide/Show files, No git changes yet,
  Hide unchanged regions / Show full file, diff toolbar titles, + Create worktree
- Fix sessionList.status.idle: "בסרלה" → "מוכן" in session.ts
- Fix text-align: left → start in message-reasoning-toggle and tool-call-io-toggle
- Fix left: 0 → inset-inline-start: 0 in attachment-chip-preview
