feat: Refactor UI and subscription logic

Introduce improved UI elements for the application name and logo. Implement enhanced subscription management and display features, including expiration checks and remaining days calculation. Update pricing for various subscription plans to reflect new offerings.

This commit also includes:
- Fixes for rendering inconsistencies.
- Refinements to the analysis view and error handling.
- Clarifications in admin dashboard user profile fields for subscription details.
