wire:click="exportPdf" attempted to return a binary Response through
Livewire's JSON channel — it re-encoded the PDF bytes as JSON and
triggered "Malformed UTF-8 characters, possibly incorrectly encoded".
Added GET /app/appointments/pdf?from=...&to=... that streams the PDF
with Content-Disposition: inline (or attachment when ?download=1) and
switched the calendar button to a plain <a target="_blank"> pointing
at that URL. The button now includes the currently visible period via
query params.
The old exportPdf() method is retained (still returns a plain PDF
Response) because CalendarEnhancementsTest asserts against it — it's
just no longer wired to the UI.
