feat(accounts): add Modify Application for rejected Current/Savings/FD/RD accounts

- Add 'Modify Application' button in kebab menu for rejected accounts (all 4 types)
- Rewrite edit components with tab-based UI matching create form
- Pre-populate all create-time values in edit form: product, account status,
  customer segment, account type, joint holders, nominees, introducer,
  deposit account link, senior citizen rate, tenure, flags (msme/balanceSwap/autoDebit)
- Fix edit mode detection using accountNo presence
- Add preselectedIntroducer @Input to IntroducerSearchComponent for pre-fill
- Support both camelCase and lowercase keys for joint holders (MySQL queryForList)
- Fix account number display: actual accountNo before previewAccountNo
- Fix cbsAccountType restore: cbsAccountType only, avoid Fineract enum object
- Add nominees fetch via /clients/{id}/nominees API in all 4 edit components
- Fix RD/FD Interest Rate Chart: SimpleChanges to prevent reset race condition
- Pre-check Senior Citizen checkbox in edit form from isSeniorCitizen DB field
- Auto-calculate rate when tenure pre-filled in edit mode
- FD calculator: use backend calculate-fd-interest API for all compounding types
- Support interestCompoundingPeriodInMonths=0 (daily) in FD calculator API
