Four small fixes on the mitra chat screen, all surfacing through the
chat connected-state.
1. AppBar customer name. The hardcoded "Customer" only ever came from
the FCM-tap navigation fallback (notification_service:
`extra: {'customerName': 'Customer'}`); the popup-overlay path passes
the real name but FCM had no way to know it. /chat/:sessionId/info
already returns `customer_display_name` — propagate it into
MitraChatConnectedData and read in the AppBar via .select. Falls
back to the route arg for the brief connecting window.
2. SISA WAKTU stuck at --:--. The pill watches a remaining-seconds
provider that's only updated by backend WS frames. Backend only
fires session_timer at 3-min + 1-min warnings + expiry, so the pill
sat at --:-- for the first ~7 minutes of a 10-min chat. Added a
local 1s ticker in the notifier that drives the provider against
expires_at (also pulled from /info). WS warning frames still
overwrite normally on top.
3. Pesan Penutup textbox. Replaced the rounded-rect OutlineInputBorder
field with a fixed-height Container pill whose border matches the
previous "shadow" tone (HaloTokens.border). Pill borderRadius is
the full 100 (was 12).
4. Goodbye textbox text was top-aligned because maxLines: 3 +
OutlineInputBorder left vertical alignment to InputDecoration's
built-in padding. Switched to maxLines: 1 + textAlignVertical:
center + isCollapsed: true inside the fixed-height container —
text now sits on the vertical center.
Bonus: the goodbye subhead "Tuliskan pesan terakhirmu untuk Customer"
also picked up the real name ("…untuk Andi Pratama").
Verified end-to-end on emulator-5556 (TestMitra-1501 + customer
"Andi Pratama"): AppBar shows Andi Pratama, SISA WAKTU ticks (04:57 →
04:35 across screenshots), goodbye pill renders with centered hint.
