refactor: use dynamic view imports

[pedrolamas]

Use dynamic imports to improve loading performance and caching capabilities

[Copilot]

Pull request overview

This PR refactors route/component loading to use dynamic imports, aiming to reduce initial bundle size and improve load-time performance/caching, while adjusting a few router-dependent call sites to avoid tighter coupling.

Changes:

• Convert router view/component registrations to lazy-loaded dynamic imports.
• Refactor authentication routing checks to use the shared $filters routing helpers instead of importing the router directly.
• Make page title generation more robust/compact by composing title parts and omitting empty segments.
