fix(ux): resolve tickets #51 #53 #54 from gitlooper sweep

- #51: Add permanent redirect /login → /auth/signin in next.config.ts
  so users/testers who type the common alias land on the correct auth page
- #53: Add "Allocations → New Planning Entry" link to empty states of
  ProjectDemandsTable and ProjectAssignmentsTable; add shortcut link in
  demands table header for canEdit users
- #54: Track confirmed dropdown selection in ResourcePersonPicker —
  green ring + checkmark icon shown when user picks from suggestions;
  cleared on any manual keypress so free-text is clearly unconfirmed
