Reorganize application into a feature-sliced architecture to improve
modularity and maintainability.

- Move shared components, hooks, and utilities into a `shared` directory
 and update all relevant import aliases and paths.
- Centralize application constants (API, app, providers, routes, storage)
 into dedicated `src/constants` files for better organization.
- Refactor page components (`DashboardPage`, `ProvidersPage`, `QuotaPage`)
 to extract business logic into dedicated presenter hooks.
- Update store implementations to align with new constant paths and remove
 redundant comments.
- Extract API response parsing logic into dedicated `services/api/parsers`
 to separate concerns within the API layer.
- Introduce `RawApiCallResponse` type for improved type safety in API calls.

feat(types): add new quota types for various providers
refactor(types): remove PROVIDERS constant and ProviderId type definition
refactor(types): remove AuthFilesResponse comment
refactor(types): import ProviderId from '@/constants/providers'
refactor(utils): remove constants.ts file

- Trigger releases on `v*` tags to align with semantic versioning.
- Enable manual `workflow_dispatch` to allow on-demand releases.
- Automate version bumping in project files to ensure consistency.
- Introduce dedicated build jobs for macOS (universal) and Linux (x64)
 to expand platform support.
- Dynamically generate `latest.json` with update information for all
 platforms to enable comprehensive auto-updates.
- Add a note to macOS releases about code signing to inform users.
