M70 (swap axes), M80 (mirror X), and M90 (mirror Y) are Excellon commands that transform coordinate interpretation for bottom-side drill files or rotated boards. They act as state toggles — issuing the same command twice cancels it. - Add swap_axis/mirror_x/mirror_y state fields to drill_state_t - Add dispatch handlers that toggle state on each M-code - Apply transforms to raw parsed coordinates before absolute/incremental store - Wire up M70/M80/M90 stats counting and UI display - Add regression test with 4 holes verifying each transform

Summary
These are state toggles — issuing the same command twice cancels it. Some CAD tools emit these for bottom-side drill files or rotated boards. Previously these had enum values and display names but no parsing or dispatch — they fell through to "unknown M-code".
