Feat: Implement Robust Hybrid Data Loading and Major App-wide Refactor

[enok1111]

This PR represents a major evolution of the application, touching three critical areas: data fetching architecture, developer operations (CI/CD and testing), and codebase modernization. It introduces a robust hybrid data loading strategy, completely revamps the CI pipeline for better reliability and speed, and executes a significant app-wide refactor to align with updated dependencies and improve code quality.

🚀 Part 1: Architectural Overhaul - Data Loading & Initialization

This is the headline feature, designed to deliver an instant loading experience when possible, while gracefully degrading to a P2P-only model when necessary.

• API-First Pre-fetching (plugins/router.ts): A new global router.beforeEach guard orchestrates all initial data loading. It performs a health check on a fast REST API; if healthy, it pre-fetches and seeds the TanStack Query cache, providing a near-instantaneous UI render.
• Graceful P2P Fallback (App.vue, composables/lensInitialization.ts): If the API is unavailable, pre-fetching is skipped. App.vue displays a smart loading screen that only appears while waiting for the P2P network to initialize and provide data.
• Non-Blocking P2P Initialization (composables/lensInitialization.ts): The lensService initialization now runs in the background via the useLensInitialization composable, preventing it from blocking the UI. Dialing logic has also been refined for better logging.
• Route-Specific Guards (plugins/router.ts): New beforeEnter guards on /upload, /admin, and /release/:id handle route protection and pre-fetching for direct navigation.
• Dynamic API URL (plugins/router.ts): A getApiUrl function now robustly parses the VITE_LENS_NODE multiaddr to construct the correct API URL for any environment.

⚙️ Part 2: Developer Operations & Testing Overhaul

This PR completely modernizes the CI/CD pipeline and testing strategy for improved feedback loops, reliability, and clarity.

• Consolidated CI Workflow (.github/workflows/ci.yml):
  • Replaced multiple, fragmented workflow files (lint.yml, tests.yml, typechecking.yml, etc.) with a single, unified ci.yml.
  • The new workflow is structured with parallel jobs for fast feedback (Lint & Type-Check, Unit Tests) and a final dependent job for comprehensive testing (Build & E2E Tests).
  • This ensures that slower, more resource-intensive E2E tests only run if the basic quality checks and unit tests pass.
• Modernized Testing Framework:
  • Removed old Vitest-based E2E tests and benchmark files (tests/*.spec.ts).
  • Introduced Playwright for modern E2E testing with a new playwright.config.ts and a basic smoke test in tests/e2e/.
  • Updated package.json scripts to separate test:unit and test:e2e commands.
  • Moved utils.spec.ts into a dedicated tests/unit/ directory.
• Improved ESLint Configuration (eslint.config.js):
  • The ESLint config has been rewritten for clarity, explicitly defining separate configurations for Browser/Vue files and Node.js/config files.
  • Added more specific ignores to prevent linting of build artifacts and test reports.
• Updated Dependencies (package.json, pnpm-lock.yaml):
  • Upgraded key dependencies, most notably @riffcc/lens-sdk (from 0.1.25 to 0.1.32) and @playwright/test.
  • This brings in the latest features, bug fixes, and security patches.

🧹 Part 3: App-wide Refactoring & UI Enhancements

These changes align the codebase with the new architecture, dependency updates, and improve overall quality.

• Type Standardization & SDK Alignment (types.ts, plugins/lensService/hooks.ts):
  • The application's core data types (ReleaseItem, FeaturedReleaseItem, etc.) have been standardized to align with the latest lens-sdk contracts.
  • All data hooks and mutations have been updated to match new SDK method signatures, data structures, and property names (e.g., endTime, to).
  • Removed outdated static data fallbacks (composables/staticData.ts).
• Enhanced UI & Permissions (views/accountPage.vue, components/layout/appBar.vue):
  • The Account Page has been completely redesigned to be more informative, now displaying user roles and a human-readable list of permissions, with a skeleton loader for a better UX.
  • The App Bar now uses detailed, computed permission checks (canUpload, canAccessAdminPanel) to accurately control the visibility of UI elements like the "Upload" and "Admin" links.
• Component & Logic Simplification:
  • HomePage.vue: The logic for creating content sections (activeSections) has been significantly simplified and made more performant.
  • Minor Fixes: Corrected icon paths in vuetify.ts, fixed category matching in releasePage.vue and categoryPage.vue, and removed the unused RegisterForm.vue.
  • Code Cleanup: Removed AnyObject types, unused SDK property imports, and updated props/state across numerous components to use the new standardized types.
• Configuration & Scripts (package.json, docs/lens_nginx.conf):
  • Streamlined package.json scripts for clarity, separating dev, build, test, and Electron-specific commands.
  • Updated the Nginx configuration template with the correct API port.

Ignore the failed gh workflows for now, they're symbolic. We'll get them fixed in further PR.
