AdityaandClaude Opus 4.7 e1d7db9b7c DSC as first-class MFA factor + branded helper UI
- m_user_mfa_factor is now the single 2FA gate. DSC enroll callback writes a
  factor row (factor_type=DSC), revoke flips disabled_on when the last cert
  goes. AuthenticationApiResource and TwoFactorAuthenticationFilter drop the
  direct m_bank_user_dsc check so disabling from the UI actually stops the
  challenge at login.
- SecurityConfig exempts /api/*/dsc/** and /api/*/mfa/factors from the
  TWOFACTOR_AUTHENTICATED gate. Without this a user with a verified factor
  can't manage their own factors after they break the device.
- MfaFactorType gains a DSC enum value; SelfUserMfaFactorServiceImpl error
  message lists it.
- dsc-helper: CBSnexora-branded header (logo, title, subtitle, accent palette),
  8-column cert table (Holder Name, Alias, Organisation, DSC Type, Serial,
  Issuer, Valid From, Expires), LdapName-based DN parsing, sign+verify proof-
  of-possession that picks SHA256withRSA / SHA256withECDSA from the key's own
  algorithm (works on RSA, RSA Signing-only, EC), pattern-matched JNLP age
  check, dscType JNLP-arg override with KeyUsage fallback.
- generate-test-dsc.ps1 produces a realistic self-signed DSC with strong key
  protection so dev testing sees real CN/O values and a PIN prompt.

AdityaandClaude Opus 4.7 8284851f67 Add DSC-based MFA: enrollment, login factor, JWS helper, tenant-scoped serving
Backend:
- m_bank_user_dsc + m_dsc_challenge tables (Liquibase 0292/0293/0294)
- DSC enrollment flow: start → JNLP → JWS helper → callback → upsert
- DSC login factor: challenge → sign → verify → claim minted TFA token
- 2FA gate now also accepts an active DSC mapping (AuthenticationApiResource
  + TwoFactorAuthenticationFilter), defensively wrapped so a missing DSC table
  doesn't 500 the auth path
- TenantAwareBasicAuthenticationFilter exempts /api/v*/dsc/helper.jar and
  strips Authorization header for that path so JWS's raw GET works without
  the user seeing a browser Basic-auth prompt
- DSC helper JAR served at /api/v*/dsc/helper.jar from a configurable
  filesystem path (default ~/.cbsnexora/dsc-helper.jar)

Java helper JAR (dsc-helper/):
- Standalone Gradle subproject, Java 8 target, fat jar with Gson shaded in
- Cross-platform token picker (Windows Cert Store / ePass2003 / eToken /
  ProxKey / Other) — matches the JNLP arg contract emitted by the backend
- Sets Fineract-Platform-TenantId on its callback POST from the JNLP args
- JNLP age check now reads cbsnexora-dsc.jnlp (current name) AND
  SignTender.jnlp (legacy) — picks the youngest, never blocks if none exist

Inline KYC upsert in updateClient (mirror of the create-flow path):
- ClientKycWritePlatformService.upsertKycInline() — creates or merges KYC
  fields, bumps status to IN_PROGRESS on real changes; resets PAN verification
  on PAN edit of a verified record
- ClientWritePlatformServiceJpaRepositoryImpl.updateClient() handles the
  kyc:{} sub-object on PUT /clients/{id}, matching createClient

User uniqueness:
- m_appuser.email + m_appuser.mobile_no UNIQUE (Liquibase 0295)
- Pre-flight assertEmailAndMobileUnique() in create/update with self-exclusion
- handleDataIntegrityIssues maps the two new constraints to clean
  field-scoped error messages (race-condition safety net)

Email OTP subject line now: "Your OTP for Login - <AppName> (dd-MM-yy-HH:mm)"
where AppName comes from fineract.email.from-name (default "CBSnexora").
