This commit removes the granular latency metrics collection and histogram visualization functionality across the codebase. The changes include:
- Removing latency histogram tracking from audio input/output processing
- Removing latency histogram UI components and related types
- Removing granular metrics collector's latency tracking capabilities
- Updating Prometheus metrics to use milliseconds instead of seconds
- Removing related tests and benchmarks
Add granular metrics collection for audio processing latency in both input and output paths. This enables better performance monitoring through histograms.
Also update build tags to include ARM platform and rename UI label for clarity.

- Create LatencyHistogram component for visualizing latency distribution
- Update audio metrics events to include histogram data
- Add comprehensive tests for histogram functionality
- Improve error handling for OPUS encoder parameter updates
- Optimize validation cache initialization
Split generic frame data validation error into specific cases for empty and oversized frames to provide better error context. The optimized validation maintains performance while improving debuggability.
Consolidate audio frame validation functions into a single optimized implementation and add dynamic OPUS encoder parameter updates based on quality settings. Initialize validation cache at startup for consistent performance.
Add latency profiler for end-to-end audio pipeline monitoring. Update test cases to use unified validation function and initialize cache.
The changes improve performance by reducing function call overhead and enabling runtime optimization of audio encoding parameters based on quality presets.
