ssd1312: enforce column addressing to prevent horizontal offset/wrap

Explicitly set column address to 0 during initialization and screen updates
to resolve intermittent ~20px horizontal offset and wrapping.

Details:
- Initialize columns to 0 in `ssd1312_configure()` via SSD1312_CMD_SET_LOW_COL(0)
  and SSD1312_CMD_SET_HIGH_COL(0).
- Reset columns for every page in `ssd1312_update()` to override residual state.
- Fixes rare display corruption caused by uninitialized column addressing in
  Page Mode, where stale column values shifted pixels horizontally.
