feat(investment,npa): RBI-grounded targets, GL-tracked interest posting, date/search pickers

- Correct Investment portfolio allocation and Loan Origination product-mix targets against
  RBI's UCB SLR/Non-SLR framework and PSL circulars, with a Target Basis column distinguishing
  RBI-mandated vs board-policy rows (Excel export included).
- Expand Investment holdings dataset with more near-term maturities so the Due-Date Diary
  reflects a realistic spread across FD/Govt Security/Non-SLR/Bond.
- Add From/To period-based Interest Calculation & Post (with GL selection for both posting and
  receiving) across the Investment Interest module, FD Entry and Bond Entry screens; fix a bug
  where a posted period kept re-appearing as due since accrual wasn't tracked per-holding.
- Add a reusable DD-MM-YYYY date-picker component and roll it out across all Investment date
  fields.
- NPA Summary Report: drop SMA-0/1/2 from the stage-wise table (kept in Day-wise Overdue only).
- NPA Recovery Report: add Account Type / NPA Category / Target-vs-Actual columns, a shared
  Account Type filter driving both the account picker and the register, and a searchable
  (fixed-position, not clipped by card overflow) account select for long lists.
