feat: implement node activation system with 1 wallet = 1 node rule

- Add complete node activation flow with burn confirmation and success/error modals
- Implement activation code generation in QNET-XXXXXX-XXXXXX-XXXXXX format (26 chars)
- Add encryption for activation codes (same as seed phrase security)
- Enforce strict 1 wallet = 1 node rule with multiple validation layers
- Add protection against script-based bypasses and race conditions
- Implement Export Activation Code feature in settings
- Add visual feedback for active nodes (disabled options, status display)
- Fix UI/UX issues with modals fitting in section without scrolling
- Remove red warning colors, use consistent blue theme
- Add detailed error messages for better user experience
