* perf(track): avoid numpy reductions on tiny box lists in position smoothing
update_position runs per tracked object per frame. While a position has
fewer than 10 samples it calls np.percentile four times, and average_boxes
(per stationary object per frame) calls np.mean four times - all on lists of
at most 10 ints, where numpy's per-call dispatch/validation overhead
dominates the actual work.
Replace them with pure-Python equivalents:
- average_boxes: sum()/len() instead of np.mean (bit-identical output)
- interpolated_percentile(): linear-interpolated percentile matching
numpy.percentile (including its lerp branch at frac>=0.5) for the small
lists used here, in place of np.percentile
Measured in the release image (numpy 1.26.4) on a 10-element list:
np.percentile 18735 ns -> 191 ns/call (98x); np.mean-based average_boxes
7480 ns -> 591 ns (12.7x); ~74 us saved per object-frame in update_position.
A live py-spy --gil profile of a camera process_frames worker showed
np.percentile (update_position) and np.mean (average_boxes) among the top
Frigate-owned on-CPU frames.
Output is unchanged: added tests assert both helpers are bit-identical to
numpy over randomized small inputs.

* Drop interpolated_percentile, keep only average_boxes
Per review: reimplementing np.percentile hurts readability and risks
divergence from numpy (e.g. numpy 2.x). Revert update_position to
np.percentile and remove the helper; keep only the average_boxes change
(sum()/len() instead of np.mean), which stays bit-identical.

video/detect.py runs these for every frame:
- get_cluster_candidates: used_boxes was a list with `in` membership tests
inside the nested loop (O(n) per check). It is only ever membership-tested,
so switching it to a set (O(1)) leaves output unchanged.
- get_consolidated_object_detections: area(current_box) was recomputed on
every inner-loop iteration though it is loop-invariant; hoist it to one
call per outer detection.
Both are bit-identical (verified against the previous implementations over
randomized inputs). Measured in the release image, get_cluster_candidates on
a frame of 30 detection boxes: 59.2 us -> 42.1 us (1.4x); the gain scales
with the number of boxes per frame.
Adds a partition-invariant test (every box index lands in exactly one
cluster).

* fix video playback stutter when GenAI dialog is open in detail stream
Inline `onOpen` callback in DetailStream.tsx:522 creates a new function identity every render. GenAISummaryChip.tsx:98's useEffect depends on [open, onOpen], so it re-fires on every parent re-render while the dialog is open. Each fire calls onSeek -> setCurrentTime -> seekToTimestamp, creating a continuous re-render + seek loop

* fix typing
* Fix the `Any` typing hint treewide
There has been confusion between the Any type[1] and the any function[2]
in typing hints.

[2] https://docs.python.org/3/library/functions.html#any
* Fix typing for various frame_shape members
Frame shapes are most likely defined by height and width, so a single int
cannot express that.
* Wrap gpu stats functions in Optional[]
These can return `None`, so they need to be `Type | None`, which is what
`Optional` expresses very nicely.
* Fix return type in get_latest_segment_datetime
Returns a datetime object, not an integer.
* Make the return type of FrameManager.write optional
This is necessary since the SharedMemoryFrameManager.write function can
return None.
* Fix total_seconds() return type in get_tz_modifiers
The function returns a float, not an int.
https://docs.python.org/3/library/datetime.html#datetime.timedelta.total_seconds
* Account for floating point results in to_relative_box
Because the function uses division the return types may either be int or
float.
* Resolve ruff deprecation warning
The config has been split into formatter and linter, and the global
options are deprecated.
