Refactor SPH TL3 to follow consistent export pattern

Changed SPH TL3 profile to use the same export pattern as all other
profile files (MIN, MID, SPH, MOD, etc.):

- Added SPH_TL3_REGISTER_MAPS dictionary export in sph_tl3.py
- Use **SPH_TL3_REGISTER_MAPS spread in __init__.py
- Removed inconsistent direct profile import approach

This matches the established pattern:
- min.py exports MIN_REGISTER_MAPS
- mid.py exports MID_REGISTER_MAPS
- sph.py exports SPH_REGISTER_MAPS
- sph_tl3.py now exports SPH_TL3_REGISTER_MAPS (consistent!)

Benefits:
- Consistent with all other profile files
- Easier to add multiple profiles per file
- Cleaner dictionary spread pattern
