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.

+ *   • Micro Enterprises: 7.5% of ANBC — mapped here to Cash Credit (MSME).
+ * RBI sets these as a % of the BANK'S WHOLE loan book (ANBC), not of any one product line's own
+ * disbursement — shown here against this module's own mix as the closest available proxy, since
+ * this demo has no bank-wide ANBC figure to check against. The remaining five products (Housing,
+ * Vehicle, Gold, Personal, Education) have no RBI-mandated minimum share of their own — Housing
+ * and Education are Priority-Sector-*eligible* within RBI's loan-amount ceilings but aren't
+ * separately targeted, and Vehicle/Gold/Personal aren't Priority Sector categories at all — so
+ * their split below is an internal business-plan assumption, not a regulatory requirement.
+ * (RBI's other PSL sub-targets — Weaker Sections 12%, overall PSL 40% — cut across products by
+ * borrower category rather than by loan type, so they aren't represented as their own row here.)
