fix: prevent axis flipping in plot_h12_calibration by adding bounds

[joshitha1808]

What problem does this solve:

In plot_h12_calibration, the X axis could flip right-to-left when zooming out aggressively because Range1d had no bounds. Also, using window_sizes[0] and window_sizes[-1] assumed a sorted list, which could cause incorrect axis ranges if the list was unsorted.

How does it solve it:

Replaced window_sizes[0] / [-1] with min(window_sizes) and max(window_sizes) to handle unsorted input.

Added bounds=(x_start, x_end) to Range1d to prevent axis inversion during pan or zoom.

Relevant issue numbers:

Fixes #648

Testing done:

Ran all tests in tests/anoph/ locally — all passed

Ran pre-commit run --all-files — all checks passed

Verified manually in a Bokeh plot that the X axis no longer flips

Breaking changes or migration notes:

No.
