Round management: tab cleanup, date pickers, advancement workflow

- Remove Document Windows tab (round dates + file requirements in
  Config are sufficient, separate SubmissionWindow was redundant)
- Restrict Jury and Awards tabs to round types that use them
  (EVALUATION, LIVE_FINAL, DELIBERATION only)
- Add Round Dates card in Config tab with DateTimePicker for
  start/end dates (supports past and future dates)
- Make Advance Projects button always visible when projects exist
  (dimmed with guidance when no projects are PASSED yet)
- Add Close & Advance combined quick action to streamline round
  progression workflow
- Add target round selector to Advance Projects dialog so admin
  can pick which round to advance projects into
