- Line 870: Rename the new TEST identifiers from PascalCase to lowercase
snake_case (e.g., change TEST(SnapshotSlotLabelsCorrect) to
TEST(snapshot_slot_labels_correct)) and update any references or registrations
accordingly; apply the same renaming pattern to the other newly added tests
flagged in this review so all TEST(...) identifiers follow the repository rule
of lowercase snake_case (ensure function names inside the test or any CALLS that
reference the test name are updated to match).
In `@tests/unit/test_command_history.cpp`:
- Around line 556-557: The tests set parameter values with expressions like
"float custom_val = od->params()[0].min_val + 2.3f; od->params()[0].value =
custom_val;" which can go out-of-range if bounds change; update these to compute
an in-range value using the parameter's min and max (e.g., midpoint: min_val +
0.5f*(max_val - min_val) or 25% in: min_val + 0.25f*(max_val - min_val)) and
assign that to od->params()[0].value (and the analogous occurrence for the other
param at the later occurrence) so undo/redo asserts remain robust.

Rename new test cases to snake_case to match repository C++ naming rules.
The newly added test case identifiers use PascalCase; in this codebase, function/method names are expected to be lowercase snake_case.

@sudip-mondal-2002, Thank you for the feedback, and apologies for the noise caused by the repeated CI failures.
