feat(investment): add portfolio allocation targets and interest receivable/post/receive lifecycle

Adds a Portfolio Allocation (Target vs Actual %) section to the Investment
Dashboard, and reworks Investment Interest into the full accrual lifecycle:
Interest Receivable, FD/Govt./Bond Interest Calculation & Post, and Interest
Receive, plus the existing registers.

Interest Calculation & Post now tracks cumulative posted/received amounts
per holding instead of recomputing full accrued interest on every click
(which previously double-counted on repeat posting). Holdings classified
Non-Performing (Sub-Standard/Doubtful/Loss) are excluded from accrual
posting per RBI norms — their interest accrues in memo/suspense only and is
recognised solely on actual cash receipt via Interest Receive.

Also bumps the production initial-bundle budget in angular.json (13/14mb ->
15/17mb) since the growing set of eagerly-loaded feature modules (Investment,
NPA, Reconciliation, GL Reports, OSS Returns) pushed the build past the old
limit.
