hide [hidden] site-wide: one [hidden] { display:none !important } in style.css

A filtered-out directory card stayed visible. The card is targeted by an
id-based ready-state selector (`.js #directory[data-dir-state="ready"]
#dirGrid > .dev-card`, two ids), which outranked the old per-element patch
`.dev-card[hidden] { display:none }` — so `card.hidden = true` set the
attribute and every card stayed on screen while the count line correctly
read "Showing 1 of 4".

Fix: one rule, `[hidden] { display:none !important }`, early in /style.css.
A class- or id-based `display` can no longer beat the attribute, so this
cannot recur with the next class that sets `display`. The per-element
`[hidden]` patches are removed so a single mechanism governs:
 - odoo-community-developers: cards + filter row + pager + modal
   (load-bearing — each sets `display`); focus-sliders/noscript (redundant)
 - index/de/es `.hero-notice[hidden]`, odoo-black-friday `.ads-consent[hidden]`
   (redundant — those elements set no `display`)
Re-fingerprint local assets (style.css changed): /style.css?v 3332fbba93 ->
061517baef across 51 pages.

Measured in a real browser (local harness, stubbed webhook; no record created,
no probe write) — computed display + geometry, never the `hidden` property:
 - filtered to one card: the other three report display:none and height 0;
   the visible set (1) equals the count line ("Showing 1 of 4") — 1 == 1
 - HEAD (pre-fix) reproduces the defect: 3 cards hidden=true yet display:flex,
   height 599.38 each; 4 visible vs the count's 1
 - pager: display:none height 0 with one page; display:flex height 66.83 with
   12 cards (Page 1 of 2); page 2 hides page-1 cards (display:none)
 - modals closed: display:none height 0; load state: cards 0, pager/empty
   display:none, filter row visibility:hidden by design
 - 375 px: same result, no horizontal overflow; avatar ask-row top identical
   across a row (2053.97 / links 2086.91)
