feat: rework GxEPDDisplay for rotation support and integrate e-ink build

- Remove fixed 128×128 virtual space and scaling; use 1:1 pixel mapping
- Display dimensions derived from panel native size + DISPLAY_ROTATION
- setCursor compensates for GFX font baseline offset (ascender per font size)
- Add getLineHeight() / getCharWidth() overrides for FreeSans fonts
- New envs: landscape (250×122) and portrait (122×250), BLE and dual variants
- Integrate all wio-tracker-l1-improvements features into e-ink build
