Subject: [PATCH 1/4] fix(filters): honor a date filter's own operator, not
 always "between"

DateBody always initialized its op state to DEFAULT_OP.date ("between"),
ignoring a def's `operators` restriction. A single-operator exact-date
filter (e.g. `operators: ["before"]`) opened on the range UI with no way
off it, since OperatorSelect hides itself when there's only one choice.
Default to the def's first allowed operator instead.

Subject: [PATCH 2/4] feat(reports): use the shared FilterBar instead of
 ReportFilters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Swaps ReportView's bespoke ReportFilters for the same FilterBar/useFilters
combo BookingRequestsPage uses — pills, saved-view-ready state, URL sync.
toFilterDefs() maps the report catalog's own filter vocabulary
(daterange/date/select/multiselect/text) onto FilterDef, matched against
every report definition's backend param handling. The search box only
shows for reports that actually implement `search` server-side, so it's
not a dead control on the rest. ReportFilters.tsx is now dead, removed.

Subject: [PATCH 3/4] fix(page-header): cap title/subtitle width

Title and subtitle grew unbounded, relying only on flex-squeeze from action
buttons to ever truncate. Caps the container at 640px and gives the
subtitle the same truncate treatment the title already had, so a long
page title or description (report descriptions in particular) always
ellipses instead of stretching the header.
