refactor(services): inline ProfileService logic into AccountViewView

Removes over-engineered ProfileService and ServiceInitializationManager
classes that were only used in one place. Inlines all profile logic
directly into AccountViewView.vue to reduce complexity and improve
maintainability.

- Deletes ProfileService.ts (325 lines)
- Deletes ServiceInitializationManager.ts (207 lines)
- Inlines ProfileData interface and methods into AccountViewView
- Maintains all existing functionality while reducing code footprint

perf(logging): convert excessive info logs to debug level

Reduces console noise by converting high-frequency, low-value logging
from info to debug level across navigation, API calls, and component
lifecycle operations. Improves performance and reduces log verbosity
for normal application flow.

- Router navigation guards: info → debug
- Plan loading operations: info → debug
- User registration checks: info → debug
- Image server rate limits: info → debug
- Component lifecycle events: info → debug
- Settings loading operations: info → debug

Maintains warn/error levels for actual issues while reducing noise
from expected application behavior.
