feat(frontend): sort planter job board by pay, deadline, altitude

[Abbyhay]

Overview

This PR adds sort controls to the Planter job board so planters can sort by highest pay rate, soonest deadline, or easiest (lowest altitude). Sort state is threaded through map types, cluster utilities, the impact map section, the map layer hook, the GraphQL schema/resolvers, and shared utilities — with stable ordering and safe fallbacks when metadata is missing.

Changes

🎛️ Job Board Sort Controls

• [ADD] apps/web/src/components/map/types.ts

  • Adds JobSortOption (payRate | deadline | altitude) and SortConfig types for map markers and cluster payloads.

• [MODIFY] apps/web/src/components/map/cluster-utils.ts

  • Clusters now receive the active sort key and order jobs within clusters before aggregating markers.
  • Cluster previews surface the top job under the selected sort (highest pay, soonest deadline, or lowest altitude).

• [MODIFY] apps/web/src/components/modules/impact-map/ImpactMapSection.tsx

  • Adds a job board sort control with options: Highest pay, Soonest deadline, Easiest (lowest altitude).
  • Wires the selected sort into the map hook and list ordering.

• [MODIFY] apps/web/src/hooks/use-map-layer.ts

  • Accepts a SortConfig and applies it to layer data before rendering; falls back to default ordering when fields are unavailable.

• [MODIFY] apps/web/src/graphql/schema.ts

  • Adds a PlanterJobSort enum and optional sort argument to job board queries.

• [MODIFY] apps/web/src/graphql/resolvers.ts

  • Resolves the sort argument with null-safe handling for missing pay rate, deadline, or altitude values.

• [MODIFY] apps/web/src/lib/utils.ts

  • Adds shared comparator helpers: sortByHighestPay, sortBySoonestDeadline, and sortByLowestAltitude.
  • Uses deterministic tie-breaking so sort order is stable across map and list views.

Verification Results

npm run typecheck
✅ 0 errors

npm run lint
✅ 0 warnings

Live acceptance check:
✅ Highest pay sort puts the highest-paying job first
✅ Soonest deadline sort puts the soonest-deadline job first
✅ Easiest (lowest altitude) sort puts the lowest-altitude job first
✅ Missing pay/deadline/altitude values are placed last without crashing

Acceptance Criteria	Status
Sort by highest pay rate	✅ Highest-paying jobs appear first in map clusters and job list
Sort by soonest deadline	✅ Deadline-ascending order with missing deadlines placed last
Sort by easiest (lowest altitude)	✅ Lowest-altitude jobs appear first with null altitude handled
Sort controls visible on job board	✅ Sort control added to ImpactMapSection and connected to map/layer state

Closes #623
