Instrument mongoose_user_cache

[jacekwegr]

This PR updates the mongoose_user_cache metrics to use mongoose_instrument. It removes old telemetry events and uses span to collect the needed information.

Code changes

• Metric migration: Changed mongoose_user_cache metrics to use mongoose_instrument.
• Telemetry removal: Removed telemetry events and replaced them with span to collect relevant information.

Testing

• Cache event checks: Added checks for cache events to the muc_light_SUITE tests, as this module uses them.
• Test updates: Added these checks to the tests where they are most relevant.
