Content-Transfer-Encoding: 8bit

Rewrites the schematic deployment pipeline from dead SchematicsService RPCs
(ForkSchematic/CreateDeploymentBinding) to the actual FfcSchematicService flow
(Create→Validate→Approve→Publish→Realize). Adds template schema validation,
variable resolution hardening, wire encoding, and centralized realization status.

New modules:
- SchematicTemplate.Schema — 7-section structural + cross-section validation
- SchematicTemplate.VariableResolver — placeholder resolution with param checks
- SchematicTemplate.WireEncoder — resolved template → FfcSchematic wire format
- SchematicClient.Behaviour — callback definitions for testability
- FfcPipeline — 12-step deploy orchestrator with step-level error reporting
- RealizationStatus — centralized status classification and display helpers

Changes:
- SchematicClient: removed fork/bind RPCs, added FfcSchematic RPCs
- RealizationPoller: delegates to RealizationStatus, persists snapshots to DB
- GuildSchematic: expanded status enum, added founding_override_expires_at
- Realization LiveView: uses RealizationStatus for all status logic
- Schematic LiveView: replaced dead flow with FfcPipeline.deploy/2

52 tests, 0 failures.
