Replace file manager toolbar buttons with hamburger menu

Removed individual delete, upload, hidden files, and refresh buttons.
Added a hamburger (☰) menu with:
- Select: toggles selection mode with checkboxes for multi-select
- Delete: enabled only when files are selected
- Upload: file upload
- Refresh: reload current directory
- Show Hidden Files: toggles dotfile visibility, persisted via localStorage

Toolbar now only has New File, New Folder, and the hamburger menu for a
cleaner interface.
