Pull request overview
This PR fixes issue #21460 by updating the ap collector to gracefully handle unknown or unparseable values in wireless station statistics, preventing collection failures when fields like "tx bitrate" contain "(unknown)" values.
Key Changes:
- Modified stationStats struct to use pointer fields, enabling distinction between missing values (nil) and actual zero values
- Removed error return from parseIwStationStatistics, allowing it to skip unparseable fields and continue processing
- Added conditional metric publishing that only includes metrics with valid values

| src/go/plugin/go.d/collector/ap/testdata/station_dump.txt | Added a third station with "tx bitrate: (unknown)" to test graceful handling of unparseable values |
| src/go/plugin/go.d/collector/ap/collector_test.go | Updated expected metrics to reflect 3 clients and recalculated averages (average_signal, bitrates) |
| src/go/plugin/go.d/collector/ap/collect.go | Refactored stationStats to use pointers, removed error handling from parsing, added helper methods for accumulating stats, and implemented nil-checks when publishing metrics |
