Refactor log view to eliminate flickering during refresh

- Use atomic update pattern in backend: collect logs into temp variable
  before replacing outputs (prevents empty state flash)
- Remove per-line x-effect directives that caused 4000+ reactive
  evaluations on every update
- Replace inline Alpine.js class bindings with CSS utility classes
- Use single $watch and morph.updated hook instead of renderTrigger
- Remove HTML entity decode cache (no longer needed)
- Fix search highlight padding that caused text shifting
