LoRA training (codai/api/loras.py):
- Fix instant crash "mat1 and mat2 have the same dtype (Half != float)":
  components loaded in their checkpoint's native dtype (fp16 text encoders +
  fp32 UNet). Force consistent fp32 (stable LoRA reference) for both SD1.5 and
  SDXL, and free VAE/text encoders after pre-encoding to keep memory in budget.

Web UI (tools/gen_township_fighters.py):
- Per-profile LoRA training launched from the Characters/Environments cards
  (steps/rank, live server progress, status badge); the "Train LoRAs" step now
  trains regardless of the consistency setting and logs what it does. Profiles
  are uploaded to CoderAI first so server-side training has reference images.
- New Matches page: final short/long videos, single clips, and outcome outputs
  per match. Re-render clips/outputs with the video model (reuses the render
  path, honoring keyframe/LoRA settings) or reassemble finals from existing
  clips (no model).
- Replace browser alert/confirm/prompt with proper in-page modal dialogs
  (uiConfirm/uiAlert/uiPrompt) on every page.
- Apply changed connection/model settings (image/video/text model) to the live
  session on Save config / Start, so per-profile jobs use them immediately.
