fix: replace explicit any types with proper TypeScript types

- Replace 'any' with 'unknown' in catch blocks and add type assertions
- Create explicit interfaces for complex objects (HostConfig, TabData, TerminalHandle)
- Fix window/document object type extensions
- Update Electron API type definitions
- Improve type safety in database routes and utilities
- Add proper types to Terminal components (Desktop & Mobile)
- Fix navigation component types (TopNavbar, LeftSidebar, AppView)

Reduces TypeScript lint errors from 394 to 358 (-36 errors)
Fixes 45 @typescript-eslint/no-explicit-any violations
