feat(ui): improve tag autocomplete toggle discoverability in prompt nodes

- Add Tag Autocomplete ON/OFF entry to the Prompt (LoraManager) node
  right-click menu, cross-referencing the slash commands
- Show the current autocomplete state (/autocomplete or /noautocomplete
  hint) below the slash command list
- Show a one-time dismissible tip in the suggestion dropdown on first use
- Clarify toggle command labels (Turn autocomplete ON/OFF) and cross-link
  all three entry points in the settings tooltip
- Share the setting write path via setLoraManagerSettingValue()
