feat(npa): add branch-wise NPA module with realistic data, pagination and recovery actions

Adds a full NPA (Non-Performing Assets) module mirroring the legacy CBS NPA
mega-menu: NPA Reports, NPA Analysis, and NPA Classification screens over a
640-account loan book classified per RBI IRAC norms (Standard through
Loss). Same Head-Office/branch-wise access pattern as the Cash/Clearing/
Transfer summary, 20-row pagination on every large table, and a Recovery
Action workflow (demand notice, SARFAESI, suit filing, OTS) on the Account
Detail screen.

Fixes several data-generation bugs so every account stays internally
consistent regardless of when it's viewed: disbursement date can no longer
predate the account's own overdue history, last-payment date now reflects
the most recent recovery entry, the quarter-ago snapshot can't imply more
overdue days than the loan's age allowed, and provision held is capped at
the account's outstanding balance.

Also fixes a text-overflow/dropdown-arrow overlap on long select options
(Investment + NPA shared form styles), and marks the GL "Financial
Statements" menu items that are already wired to a working dialog.
