Feat/crowdfunding (#650)

* feat(bounty): features/bounties data layer (types, keys, draft + escrow) (#596)

Adds the features/bounties/ data layer for the v1 app, mirroring
features/hackathons/. REST-only via the typed openapi-fetch client; every
server shape is aliased from the backend-generated schema so it cannot drift.

- types.ts: aliases the generated draft + escrow DTOs (BountyDraft,
  UpdateBountyDraftBody, the four section types, BountyEscrowOpResponse,
  PublishBountyEscrowRequest, ...). Derives the two-axis taxonomy from the
  generated mode DTO, superseding the local stubs in the ModeTab.
- api/keys.ts: bountyKeys factory.
- api/draft-client.ts + use-draft.ts: imperative CRUD plus the
  useDraft / useDraftList / useCreateDraft / useUpdateDraft / useDeleteDraft
  hooks against /organizations/{organizationId}/bounties/draft[/{id}] + /drafts.
- api/escrow-client.ts + use-escrow.ts: organizer escrow calls (publish /
  cancel / select-winners / submit-signed / poll) plus useEscrowOp +
  useEscrowOpRunner, mirroring the hackathon machinery (MANAGED polls; EXTERNAL
  signs -> submit -> poll) bounty-scoped.
- index.ts: public surface.

Regenerates lib/api/generated/schema.d.ts from the v2 backend so the bounty
draft paths/DTOs are present.

* feat(bounty): wizard shell + step/draft machinery (#598)

Adds the bounty Configure wizard orchestrator and its step + draft state,
mirroring the hackathon wizard. No AI assist.

- components/organization/bounties/new/constants.ts: StepKey
  (scope/mode/submission/reward/review), STEP_ORDER, BountyFormData, and
  isBountyStepDataValid.
- hooks/use-bounty-steps.ts: URL ?step= navigation (free-roam) with a
  presentational step-status map.
- hooks/use-bounty-draft.ts: lazy create (ensureDraftId) then per-section PATCH,
  resume via useDraft, and transformBountyFromApi (sections -> form state;
  winnerCount derived from prize tiers, ISO dates trimmed for the inputs).
- components/organization/bounties/new/NewBountyTab.tsx: orchestrator wiring
  steps + draft + per-step save, persisting ?draftId= for resume, and threading
  the chosen mode from ModeTab into SubmissionModelTab.

Scope/Reward/Review tabs (#600) and the publish + funding flow (#601) are left
as marked placeholders with their save/navigate/draftId seams in place; this
satisfies the acceptance criteria (navigate, autosave, resume) without
speculative publish UI that depends on the unbuilt publish hook.

* feat: implement multi-step crowdfunding campaign wizard with milestone management

* feat(crowdfunding): v2 public pages, builder dashboard, milestone tracking

- Redesigned public listing (ProjectCard) and detail page with proper
  lifecycle states, voting panel, contributor list, and fully-funded detection
- Added public milestone list + detail pages under /crowdfunding/[slug]/milestones
- Builder per-campaign management: tabbed layout (overview / milestones /
  contributions) with shared header showing milestone X/Y progress and
  Fully Funded badge once fundingRaised >= fundingGoal
- Milestone status sourced from milestoneState() utility: claimedAt-based
  "paid out" detection replaces stale reviewStatus === 'completed' checks
- CampaignStatusBanner: shows milestone delivery bar and Fully Funded label
  during the FUNDING phase when goal is reached
- milestones-metrics: completedAmount correctly sums paid-out milestones;
  inProgress checks SUBMITTED/UNDER_REVIEW enum values
- ProjectCard: switches from funding bar to milestone X/Y bar on fully funded;
  footer and status badge update to Fully Funded (green)
- lib/crowdfunding/status.ts: single source of truth for all campaign and
  milestone status copy and tone

* chore: update lockfile dependencies for package-lock.json

* refactor: standardize API error extraction to support array-based messages across crowdfunding components

* refactor: restructure StoryStep inputs, enable sidebar navigation, and update campaign wizard validation logic

* feat: replace textarea with AnnouncementEditor and add markdown rendering for campaign project details

* fix: useCampaign routes UUID params to fetchCampaignById

Post-create redirect lands on /me/crowdfunding/{uuid}. The hook was
always calling the slug endpoint which rejected UUIDs. Now detects
UUID format and uses the correct /api/crowdfunding/{id} endpoint.

* feat: auth-gate voting/contribute + branded fallback banner

- VotePanel: unauthenticated users see "Sign in to vote" instead of
  the yes/no buttons
- Public page: "Back this project" replaced with "Sign in to back this
  project" link for unauthenticated visitors
- Fallback banner (no banner set): full-height Boundless-branded SVG
  with dot grid, concentric arcs in brand colour, and faint wordmark
  instead of the flat zinc gradient div
