Merge dev into demo-backup

Brings in all of dev's latest content not present on demo-backup
(Share Withdrawal/Closure feature, TDS reports, KYC exception tracking,
client-edit-email-dialog, form121 tab, search-select) while preserving
demo-backup's own unique changes (wrapping Approval Center tab nav,
Loan Origination/Investment mega-menus). 36 files that a prior "ours
wins" conflict resolution had silently dropped were restored explicitly
from dev's tip.
