[Feature] 2 pages by role staff role page for making counter items

Staff page
- staff makes a list of things to track, lets remake meal tally as example
- tracking children handed meals, teens, & adults if any
- tracking how many meals total, leftover from previous, new incoming, how many left after this event
- volunteer sign wetmark - maybe not as needed from volunteer but maybe from staff report however i think it was required
- submit

VOlunteer page
- see list of available tally events
- choose one (will be list of one for now)
- view the tallyup page to start the tallying

The issue names staff and volunteer pages but no files, tests, or entry points. Start by locating the TypeScript application's existing page and role-handling entry points, then clarify the tally event and sign-off requirements. Done means both role-based flows support creating or selecting an event and completing the described tally submission.
