fix(13e6): SPI corruption fix + setup-screen polish

- SPI corruption: lower clock to 4 MHz (matches 7.3" prod) and push from
  internal SRAM in 8 KB chunks instead of streaming directly from a PSRAM
  scratch buffer. On the S3, Arduino's SPI DMA reads RAM directly — the
  CPU's cache can hold writes to PSRAM that the DMA never sees, painting
  the panel yellow/garbage. Internal-SRAM chunks are DMA-coherent.
- LittleFS partition: switch the env to default_16MB.csv. The stock
  partition table for esp32-s3-devkitc-1 reserves ~1.5 MB for SPIFFS;
  three 960 KB setup-screen .bin files need ~2.9 MB + LittleFS metadata.
- Setup screens: redesigned to match the 7.3" information density —
  yellow header band, two-column body with vertical divider, "Connect to
  WiFi" heading + 5 numbered steps + manual QR + side label on the left,
  Step 1 / Step 2 QRs on the right.
- Orientation diagrams: PORTRAIT drawn upright (ribbon-bottom, up-arrow);
  LANDSCAPE drawn pre-rotated 90° CCW so it snaps to upright landscape
  when the user rotates the frame 90° CW (ribbon-bottom + left-arrow in
  portrait view → ribbon-left + up-arrow after rotation). "LANDSCAPE"
  label runs vertically up the long edge so it reads horizontally once
  the frame is mounted landscape.
- New helper paste_rotated_text() — PIL's text() can't rotate, so render
  → rotate → paste-with-alpha. Used for the vertical LANDSCAPE label.
