dashboard — vrai tableau + probe viser_url alive + CSS propre

1. _jobs_table.html: remplace la liste <li>flex par un vrai <table> avec
   colonnes explicites: status · preview · #id · AUV+GP · label · duree
   video · frames · hors-eau · progression · temps · actions. Stitches
   restent en <ul> compacte.

2. main.py _build_acquisitions: probe TCP le viser_url avec cache 8s
   avant de le passer au template. Si port mort -> d[viser_url]=None ->
   pas de bouton affiche. Fini les liens qui mennent a rien.

3. style.css: purge des regles flex conflictuelles, rewrite propre pour
   table.jobs-table, badges, prog-bar, btn-viser direct link.
