Remove debugging console.log statements

Clean up all temporary debugging console.log statements added during
registration status troubleshooting. Remove debug output from multiple
components while preserving essential error logging and functionality.

Changes:
- PlatformServiceMixin.ts: Remove debug logging from $saveUserSettings and $saveMySettings
- AccountViewView.vue: Remove debug logging from mounted, initializeState, checkLimits, and onRecheckLimits
- UsageLimitsSection.vue: Remove debug logging from lifecycle hooks and recheckLimits
- IdentitySwitcherView.vue: Remove debug logging from switchAccount method

All core functionality preserved including error handling with logger.error()
and user notifications. Codebase now production-ready without debugging noise.
