Phayriosis Reborn Continued 0.0.16 - Phase 6 large impact + meteor chunk lease

User-tested 0.0.15 impact foundation worked, but distant meteors stopped ticking outside player simulation range and the impact/core were too small.

0.0.16:
- impact range 210-250 blocks
- render scale 80x
- real explosion power 20
- core 15x8 radii, infection radius 42
- temporary Forge ticking chunks along flight corridor + 7x7 impact zone
- lease coordinates persisted in meteor NBT
- ticket release delayed 90 ticks after impact
- core/infection terrain writes batched across server ticks
- superflat minimum-Y core clipping corrected

Do not replace temporary chunk leases with permanent forced chunks, and do not collapse batched terrain deposition into one tick.

Startup stale-ticket safety:
- Added PhayriosisMeteorChunkTicketValidation on the MOD event bus.
- Common setup registers ForgeChunkManager loading validation.
- If saved event state says activeMeteor=true, meteor UUID tickets are retained for resume.
- If activeMeteor=false, any persisted Phayriosis entity chunk tickets are stale and removed on world load.
- This covers save/quit during the short post-impact delayed-release window.
