Add moveTabToPanel setting for configurable tab drop position

[Victor239]

Implements #2175: Users can now configure where tabs land when dragged to a panel.

Changes

New setting: moveTabToPanel in Drag and Drop settings

• Options: 'start' | 'end' (default: 'end')
• Controls tab placement when dropped to panel area (not between specific tabs)

Modified getDstIndexInside() logic:

// Before: always used nextTabIndex (end of panel)
return dstPanel.nextTabIndex ?? Tabs.list.length

// After: respects user preference
return Settings.state.moveTabToPanel === 'start'
  ? dstPanel.startTabIndex
  : (dstPanel.nextTabIndex ?? Tabs.list.length)

Files changed:

• src/types/settings.ts - Type definition
• src/defaults/settings.ts - Default value and options
• src/page.setup/components/settings.dnd.vue - UI control
• src/_locales/dict.setup-page.ts - i18n (9 languages)
• src/services/drag-and-drop.actions.ts - Drop logic

Precise positioning (dropping between specific tabs or onto parents) is unaffected.
