feat(investment): add Treasury Investment module (FD, Govt Sec/Non-SLR/Bond/MF, Share)

Adds full frontend-only Investment module mirroring the legacy AutoBank CBS Investment menu: Dashboard, FD/Bond/Share entry screens (purchase, interest, sell/redeem, write-off, amortize and more), 10 master screens, an Interest calculation/register screen, and ~21 reports. All figures are derived from a single holdings/transactions dataset so entry, interest, and reports can never drift out of sync. Wires the new "Investment" mega-menu into the shell and routes the previously inert Investment stub buttons.
