feat: calendar enhancements — view modes, post CRUD, PDF, list

Closes 5 user-requested features in /app/calendar-board:

1. View mode switcher: Zi / Săpt / Lună / Custom / Listă
2. Editable post names + assignable default master per bay
3. Quick-add bay (+ Pod nou) from calendar toolbar — supports yard
   spaces without a lift ("Curte 1", "Atelier electric")
4. PDF export of programări for printing
5. Inline list view alongside the matrix view

== View modes ==
$viewMode: day | week | month | custom | list

- Day view: 1 column, just today (or navigated day). Shift moves day by day.
- Week view: current 7-column matrix (unchanged default).
- Month view: 30/31 columns shown smaller (70px each). Shift moves by month.
- Custom: 2 date pickers for arbitrary start..end range (max 31 days).
- List view: flat sortable table with Data/Ora/Subiect/Client/Telefon/
  Auto/Pod/Maistru/Status columns. Click row → opens detail panel.

getDays() computes the right day count + start anchor for each mode.
setViewMode() snaps weekStart to the right anchor (startOfMonth, today,
startOfWeek). shiftWeek delta semantics adapt: day mode shifts 1 day,
month mode shifts 1 month, others shift 7 days.

== Editable posts + default master ==
New PostResource (/app/posts) in Admin group: full CRUD with name,
color, hours_per_day, default_master_id, description, is_active,
sort_order. Gated by ADMIN_SETTINGS_EDIT.

Migration: posts.default_master_id FK → users (nullOnDelete).

Inline rename from calendar: click any post's row label opens a modal
with name field + default master dropdown. Saved values propagate
immediately to next appointment creation.

Auto-fill in new appointment: when creating an appointment via the "+"
cell button on a post row, master_id is pre-filled from
post.default_master_id (if not already set by groupBy='master' row).

== Quick-add bay ==
"+ Pod nou" button in toolbar opens a small modal (no full page nav):
name, color picker, hours/day, description. createPost() saves and
refreshes the row list. Designed for "yard space" use-cases — names
like "Curte 1" or "Atelier electric" are first-class, not workarounds.

== PDF export ==
"🖨 PDF programări" button calls exportPdf() which uses the existing
dompdf integration (already installed). Renders pdf/appointments.blade.php
grouped by day with table per day showing time/title/client+vehicle/
post/master/status. Romanian date headers ("Marți, 10 Iunie 2026").
streamDownload with filename programari_YYYY-MM-DD_YYYY-MM-DD.pdf.

== List view ==
getListAppointments() returns flat array of all appointments in the
visible period (date-range respects current viewMode), with full
client/vehicle/post/master joined. Status filter respected. Row click
opens the existing event detail panel.

== Tests ==
CalendarEnhancementsTest (8):
- viewMode='day' returns 1 day
- viewMode='month' returns 30 days for June 2026
- viewMode='custom' uses customStart..customEnd range
- quick-add post via Livewire createPost persists with all fields
- rename post updates name + default_master_id
- new appointment auto-fills master_id from post's default_master_id
- list view returns flat array with phone + post name joined
- exportPdf returns StreamedResponse with .pdf filename

Suite: 285 passed (802 assertions). Was 277.
