v1.4.0

Co nowego:
- Wsparcie Active Directory dla LDAP (obok LLDAP/OpenLDAP), przełącznik typu
  katalogu w Admin > Integracje.
- Wyszukiwarka klientów dla operatora (Operator > Klienci).
- Stronicowanie kolejki operatora (50/stronę) i dashboardu klienta (20/stronę).
- Globalna wyszukiwarka zgłoszeń (Ctrl+K/Cmd+K) z operatorami w stylu Gmaila
  (od:, temat:, treść:, numer:), plus przycisk "Szukaj" w panelu bocznym.
- Ostatnio przeglądane zgłoszenia w panelu bocznym operatora.
- Przeprojektowany pasek nawigacji: suwak Klient/Operator/Administrator
  zamiast rozwijanego menu, bogatsze menu profilu (nazwa/e-mail/role),
  dynamiczne tytuły kart przeglądarki na każdej podstronie.
- Narzędzie do jednorazowego importu historii zgłoszeń z Heska 3.x
  (scripts/hesk-import/).
- Poprawka: paginacja pokazywała surowe klucze tłumaczeń zamiast tekstu
  (brakujący lang/pl/pagination.php).

+## [1.4.0] - 2026-08-05
+
+### Added
+
+- **Active Directory support for LDAP auth** (Admin > Integracje > "LDAP /
+  Active Directory") — a "Typ katalogu" dropdown switches between LLDAP/
+  OpenLDAP (the original, still the default) and Active Directory. AD uses a
+  different schema (no inetOrgPerson/posixAccount, a binary `objectGUID`
+  instead of `entryUUID`) and login attribute (`sAMAccountName`, not `uid`);
+  both are now auto-detected from the directory type instead of requiring
+  LLDAP's schema everywhere.
+- **Operator client search** (Operator > Klienci) — a dedicated search page
+  (name or e-mail, any account, not just role=client) showing each match's
+  role badges and ticket count, linking straight into the queue pre-filtered
+  to that customer.
+- **Paginated ticket lists** — the operator queue (50/page) and client
+  dashboard (20/page, current/archive tracked as separate pages so switching
+  tabs doesn't lose your place) no longer render every matching ticket at
+  once; sorting still happens over the full filtered result first.
+- **Command-palette global search (Ctrl+K / Cmd+K)** — searches tickets from
+  anywhere in the app, scoped to what the searching user can actually see
+  (operators/admins search everything visible to them, clients only their
+  own). Supports Gmail-style operators — `od:` (reporter), `temat:`
+  (subject only), `treść:`/`tresc:` (message content only), `numer:`/`nr:`
+  (ticket number), combinable and AND'd together (`od:kacper
+  temat:drukarka`) — plain text with no operator still searches everything
+  as before. A "Szukaj" button in the operator/admin sidebars opens the same
+  dialog for anyone who doesn't know the shortcut.
+- **Recently viewed tickets** (operator sidebar) — the last 6 tickets an
+  operator actually opened, most-recent first, re-bumped (not duplicated) on
+  a repeat visit.
+- **Navbar redesign: panel switcher.** The old dropdown-only role switcher
+  (in the profile menu) and the plain "Panel Klienta/Operatora/Administratora"
+  text label are replaced by a single segmented control centered in the top
+  bar — Klient / Operator / Administrator — showing only the areas the
+  logged-in user actually holds, highlighting the current one, and sliding a
+  preview to whichever option is hovered before you click. Adapts to a
+  full-width row below the icons on narrow screens instead of overlapping
+  them.
+- **Richer profile dropdown** — now shows the account's name, e-mail, and
+  role badges above the existing Powiadomienia/Wyloguj się links.
+- **Per-page browser tab titles** — every page sets its own `<title>`
+  (e.g. the ticket subject, the selected queue, the active admin tab)
+  instead of every tab just showing the company name, always anchored with
+  the company name as a suffix so it's still identifiable once the browser
+  truncates a long tab title.
+- **Hesk 3.x historical import** (`scripts/hesk-import/`) — a one-time,
+  read-only migration of tickets (with full reply/note history) from an old
+  Hesk helpdesk database, filtered by e-mail domain. Dry-run by default,
+  resumable, auto-maps categories (exact name match) and teams (when
+  unambiguous). See `scripts/hesk-import/README.md`.
+
+### Fixed
+
+- Pagination controls ("« Poprzednia" / "Następna »") were showing the raw
+  translation keys `pagination.previous`/`pagination.next` instead of
+  actual text — the app's `APP_LOCALE=pl` had no matching `lang/pl/`
+  translation file and no English fallback (`APP_FALLBACK_LOCALE` is also
+  `pl`), so Laravel had nothing to resolve those strings to.
