Frontend counterpart to the backend dual-OTP contact-change feature:
- New ContactOtpBlockComponent (6-box segmented OTP input) used up to 4x in
Edit Client (old/new mobile, old/new email — grouped under per-field
sub-headers) and once each for mobile/email in Create Client, gating
Save/Save & Next until every required box is verified.
- edit-client.component.ts: detects mobile/email/DOB changes against the
loaded snapshot using local-date comparison (not `.toISOString()`, which
false-triggers a day-shift in positive-UTC-offset timezones) and
trimmed/case-insensitive email comparison (autofill whitespace or re-typed
casing no longer reads as a change the masked preview can't explain).
- client-kyc-step.component.ts: new `invalidFieldLabels` getter names every
currently-invalid required KYC field, surfaced via the Save & Next tooltip
in both create-client and edit-client so a greyed-out button always
explains what's still missing instead of a generic message.
- CaptureImageDialogComponent generalized for both profile photo and
signature (photograph-a-paper-signature) capture:
- Frame aspect now matches the requested getUserMedia resolution
(4:3 profile / 16:9 signature) with object-fit: cover, eliminating the
pillarboxing (black bars) a mismatched box previously caused.
- Suppresses Chromium's auto-injected PiP/cast corner overlay icons.
- Frame height capped in vh (not just px) so the dialog fits short
viewports instead of pushing Cancel/Upload below the fold.
- upload-document-dialog.component.ts: generic Documents-tab upload now also
offers "Capture from Webcam" alongside Browse, reusing the same capture
dialog.
- New client History tab (reuses the existing Audit Trail data, scoped to
this client) and dataUrlToFile/dataUrlToBlob util for routing webcam
captures through the same upload pipelines as a picked file.
