DR-042 Phase C (legibility, part 1): expedition objective HUD, Aether button, cold-start seed, Biomass sink, palette declutter

Scoping/design-gated (wf_7c5a555e-136). Fixes "the base reads as inert after Phase A":

- C7b objective readout: new replicated ExpeditionObjective{[GhostField] byte State, short Remaining} on the
  untagged CycleDirector ghost (cross-region safe). Sole writer ZoneEnemyDirectorSystem, written ABOVE its
  early-returns (snapshot-above-early-return) so the HUD never freezes stale. Play-verified it replicates
  server->client.
- C7a gate prompt + C7b HUD readout: HudSystem shows "GO TO THE EXPEDITION GATE" / "EXPEDITION IN PROGRESS - N
  remaining" / "CLEARED - return to claim", below the siege/overrun overrides.
- C6a Aether upgrade button: un-gated BuildSendSystem.UpgradeAbility (was #if UNITY_EDITOR); HudSystem adds a
  MenuUi.Button with live affordability tint (the only Aether sink was U-key only).
- C6c cold-start seed: CycleDirectorSpawnSystem seeds Tuning.StartingOre (50) into the ledger on a NEW game only
  (born-correct, pre-Playback), killing the silent turret-before-fabricator deadlock. Play-verified seededOre=50.
- C6b Biomass sink: Wall cost Ore->Biomass (the dead currency now has a home). Play-verified WallCostRes=Biomass.
- C6d palette declutter: hide dead Pylon/Harvester/Conveyor from the build palette + trimmed their dev hotkeys
  (catalog/prefabs stay baked, code-intact per DR-020).

389/389 EditMode + clean netcode Play smoke (ghost re-hash OK, no exceptions). SaveData stays v5.
C5 (walls block enemies) is the remaining Phase C item, sequenced separately.
