Gate `size_to_values()` on macOS in `_axes.py`

NOTE, this reversion was discovered as needed by @goodboy after
extensively manually testing the new zoom-by-font-size feats introduced
alongside macOS support.

Use class-body `if _friggin_macos:` branching to
conditionally define `size_to_values()` for both
`PriceAxis` and `DynamicDateAxis` — macOS gets the
new `_updateWidth()`/`_updateHeight()` + geometry
recalc path, other platforms fall back to the
original `setWidth()`/`setHeight()` calls.

Deats,
- add `platform` import and module-level
  `_friggin_macos: bool` flag.
- `PriceAxis.size_to_values()`: macOS branch calls
  `_updateWidth()` + `updateGeometry()`; else branch
  uses `self.setWidth(self.typical_br.width())`.
- `DynamicDateAxis.size_to_values()`: macOS branch
  calls `_updateHeight()` + `updateGeometry()`; else
  uses `self.setHeight(self.typical_br.height() + 1)`.
- reorder imports: `platform` before `typing`.
