Header: show Civi stage label prominently; restore current_stage readonly in Stage 0

- New STAGE_OPTION_GROUP_ID constant (=75) added to config and consumed
  by both the in-card readonly and the header. Because the field carries
  optionGroupId, /api/data auto-includes the Stage option group in its
  parallel fetch (via the existing optionGroupIds derivation).
- SubmissionContextHeader: dropped the small inline 'Stage Organizing'
  line. Replaced with an uppercase 'Current stage' eyebrow next to the
  progress dots, followed by a display-font 20/24px leaf-toned label
  underneath. Resolves the stored option value ('Organizing') to its
  Civi option label ('Stage 1 — Convene & Prepare') via the new
  resolveStageLabel helper; falls back to the raw value if the option
  group hasn't loaded.
- Stage 0 'Check-in (organizing)' section: re-added a current_stage
  readonly field at the top. With optionGroupId set, FieldRenderer's
  readonly branch resolves the value to the Civi label for display.
