Rewrite label designer as an item-based canvas editor

Browse Source 
- Items (text blocks, emoji) are placed freely: click to select, drag to
  move, arrow-key nudge, rotate to any angle, resize, duplicate, fit/center
- Emoji picker now covers the full emoji set via emoji-data-python
  (~1,900, 9 categories, name search, hover shows the name); thumbnails
  are rendered by Pillow with Noto Color Emoji so ZWJ sequences and flags
  display exactly as they print
- Designs save/open as JSON; last design restored on launch

- Live 1-bit preview shows exactly what the printer will produce - **+ Text** adds a text block; click any emoji in the picker (all ~1,900, searchable by name) to add it
- Auto-fit shrinks the font until the text fits the label - Click an item to select it, drag to move, arrow keys nudge (Shift = 10 px), Delete removes
- Printer model / connection / address / density are remembered in `~/.config/niimprint-label/settings.json` - Selected item panel: edit text, size, angle (any degrees, or the ⟲/⟳ 90° buttons), X/Y, bold, alignment
- **Fit** resizes the item to fill the label; **Center H/V** aligns it
- The canvas shows the dithered 1-bit image exactly as the printer will produce it
- **Save…/Open…** store designs as JSON; the last design and printer settings are restored on launch
Fonts: DejaVu Sans (`/usr/share/fonts/TTF/`) for text and Noto Color Emoji (`/usr/share/fonts/noto/`) for emoji; edit `TEXT_FONTS` / `EMOJI_FONT` at the top of the file for other distros. Fonts: DejaVu Sans (`/usr/share/fonts/TTF/`) for text and Noto Color Emoji (`/usr/share/fonts/noto/`) for emoji; edit `TEXT_FONTS` / `EMOJI_FONT` at the top of the file for other distros. Emoji are rendered by Pillow with the same font that prints, so the picker is WYSIWYG.
