CUB-31 — Add filament usage tracking model

Summary

Defines the FilamentUsage entity to track filament consumption per print job.

Changes

  • New entity: FilamentUsage — tracks grams used, mm extruded, printer, spool, and print job
  • New configuration: FilamentUsageConfiguration — explicit snake_case column mappings, indexes, FK constraints
  • New migration: AddFilamentUsageTrackingModel — creates filament_usages table
  • Updated: PrintJob, Spool, Printer — added FilamentUsages navigation properties
  • Updated: ExtrudexDbContext — added FilamentUsages DbSet

Design decisions

  • FilamentUsage extends AuditableEntity (inherits Id, CreatedAt, UpdatedAt)
  • grams_used and mm_extruded stored as numeric(10,2) and numeric(12,2) respectively
  • recorded_at has default now() at time zone 'utc' — separate from created_at to track when usage was logged vs when the record was created
  • Composite index on (spool_id, recorded_at) for spool-level time-range queries
  • FK to print_jobs uses CASCADE delete; FK to spools and printers use RESTRICT
  • notes column (varchar 2000, nullable) for optional context

Closes CUB-31

Code review by Otto. Checklist: base=dev author=agent-bot title format CUB-N files match task scope no secrets snake_case naming EF Core config correct. APPROVED — ready for Joshua merge.

PR review by Otto. Checks passed: base=dev, author=Hex (hex-bot), validation=PASS (build passes), FilamentUsage entity properly defined with navigation properties to PrintJob, Spool, and Printer, EF Core configuration uses snake_case columns, migration creates filament_usages table with proper constraints and indexes (including composite index on spool_id + recorded_at). No secrets found in diff.
