v1.5.0

Co nowego:
- Podgląd logów w panelu admina (Admin > Logi) — pliki storage/logs/*.log
  bez potrzeby dostępu do kontenera, z filtrami poziomu/tekstu/liczby wpisów
  i auto-odświeżaniem.
- Filtr „Bez kategorii” w kolejce operatora — izoluje zgłoszenia bez
  przypisanej kategorii/podkategorii.
- Narzędzie importu z Heska: już nie tworzy automatycznie kont klientów dla
  nieznanych e-maili (pomija takie zgłoszenia zamiast zakładać konto),
  łączy odpowiedzi/właścicieli zgłoszeń z realnymi kontami operatorów po
  e-mailu, nowe flagi --assign-operators i --fix-closed-dates do
  donaprawiania wcześniejszych importów, dedykowany log
  storage/logs/hesk-import.log.
- Poprawka: pulpit statystyk operatora (rozkład wg kategorii/podkategorii i
  filtr kategorii) pomijał zgłoszenia przypisane do samej kategorii bez
  podkategorii (np. z poczty IMAP) — teraz liczone poprawnie.
- Poprawka: błąd JS i zawieszone w tle liczniki przy nawigacji z widoku z
  aktywnym licznikiem (najbardziej odczuwalne w liczniku czasu pracy
  operatora).
- Porządki w bazie: usunięte niewykorzystywane kolumny
  (users.remember_token, users.email_verified_at,
  email_templates.trigger_label); wartości pól dodatkowych, stan
  triage/podsumowania AI i powiązany sprzęt Snipe-IT przeniesione z tabeli
  tickets do osobnych tabel (ticket_field_values, ticket_ai_summaries,
  ticket_snipeit_assets) — bez zmiany zachowania, ale pola dodatkowe są
  teraz efektywnie przeszukiwalne; dodane brakujące indeksy na 4 tabelach
  pivot; tickets.source/ticket_messages.source walidowane względem znanego
  zestawu wartości.

+## [1.5.0] - 2026-08-05
+
+### Added
+
+- **Admin log viewer** (Admin > Logi) — browse `storage/logs/*.log` from the
+  admin panel without shell access to the container: a file picker (size +
+  last-modified, most recent first), level/free-text/entry-count filters, and
+  an optional 5s auto-refresh. Read-only, admin-only; reads only the tail of
+  large files to keep it fast.
+- **"Bez kategorii" filter** in the operator queue's category dropdown —
+  isolates tickets with neither a category nor subcategory assigned (e.g. an
+  IMAP mailbox routed to nothing in particular), previously only reachable by
+  scanning the unfiltered list.
+
+### Changed
+
+- **Hesk import tool** (`scripts/hesk-import/`) no longer auto-creates client
+  accounts for unrecognized requester e-mails — the servicedesk user base is
+  now treated as authoritative, so a Hesk ticket whose requester has no
+  matching account is skipped instead (reported at the end, with the list of
+  skipped e-mails). Hesk staff replies/notes and ticket ownership are now
+  linked to real operator/admin accounts when the staff e-mail matches one.
+  Two new backfill flags cover tickets imported before these existed:
+  `--assign-operators` (sets `assignee_id` from Hesk's ticket owner, never
+  overwriting a manual reassignment) and `--fix-closed-dates` (corrects a
+  closed ticket's date to Hesk's own `closedat` column instead of the
+  drifting `lastchange`, and adds the missing "Zamknięte" history entry).
+  Every newly imported ticket also records its source Hesk id
+  (`tickets.hesk_ticket_id`, unique) as a second, DB-level guard against
+  duplicate imports on top of the existing state file. See
+  `scripts/hesk-import/README.md` for details.
+- Internal database cleanup: removed three columns confirmed unused against
+  live data (`users.remember_token`, `users.email_verified_at`,
+  `email_templates.trigger_label`); moved custom field values, AI
+  triage/summary state, and the linked Snipe-IT asset off the `tickets` row
+  into three dedicated one-to-one tables (`ticket_field_values`,
+  `ticket_ai_summaries`, `ticket_snipeit_assets`) — no visible behavior
+  change, but custom field values are now efficiently queryable instead of
+  living only in a JSON blob, and the `tickets` row itself is narrower; added
+  missing reverse indexes on 4 pivot tables (`team_subcategory`, `role_user`,
+  `team_user`, `custom_field_subcategory`); `tickets.source` and
+  `ticket_messages.source` now validate against a known set of values
+  instead of silently accepting any string.
+
+### Fixed
+
+- The operator statistics dashboard's category/subcategory breakdown (and
+  its category filter) only counted tickets routed through a subcategory —
+  a ticket routed to a whole category with no subcategory (e.g. via an IMAP
+  mailbox routed to "całą kategorię") was silently excluded from those
+  charts and from filtering by that category. Now counted correctly, with
+  bare-category tickets shown as their own "(bez podkategorii)" row in the
+  subcategory breakdown.
+- A JavaScript error (and stray background timers left running) could occur
+  when navigating away from a page with an active countdown/timer widget —
+  ticket/queue auto-refresh, the theme switcher, file-attachment
+  drag-and-drop. Most consequential in the operator ticket time tracker,
+  where it could throw console errors and momentarily break other UI
+  elements (e.g. dropdown menus) after leaving a ticket with the timer
+  running.
