improve ui zoom defaults

Again a patch (vibed) from our very own @dnks
(just a commit msg reworking using his new `/commit-msg` skill added by
@goodboy B)

Deats,
- add `Axis.update_fonts()` to recalculate tick font, text offset,
  bounding rect and `pyqtgraph`'s internal text-width/height tracking
  after a zoom change; store `_typical_max_str` at init for later reuse.
- rework `PriceAxis.size_to_values()` and
  `DynamicDateAxis.size_to_values()` to use pyqtgraph's
  `_updateWidth()`/`_updateHeight()` with `updateGeometry()` instead of
  raw `setWidth()`/ `setHeight()` so auto-expand constraints are
  respected.
- fix `GlobalZoomEventFilter` to mask out `KeypadModifier` and
  explicitly require both Ctrl+Shift, letting plain Ctrl+Plus/Minus pass
  through to chart zoom.
- add `_update_chart_axes()` to walk all plot-item axes during
  `_apply_zoom()` and call `splits.resize_sidepanes()` to sync subplot
  widths.
