fix(entity): restore blaze flight parity

[CompileRider]

Problem

Blazes currently experience gravity like ground mobs instead of keeping their expected hovering movement. This breaks vanilla parity and makes blazes fall off ledges instead of staying airborne.

What changed

• override the existing mob airborne movement hooks for BlazeEntity
• set blaze gravity to 0.0 and its Y-velocity drag to 0.6
• add a focused regression test that verifies blaze no longer shares the same gravity/drag shape as a normal grounded mob

Testing

• cargo fmt --check
• cargo clippy --workspace --all-targets --all-features -- -D warnings
• cargo test
• cargo audit check

Fixes #1960

blaze still have gravity and y velocity only multiply by 0.6 when it falling

I don't think the changes resemble vanilla behavior. Please look at latest vanilla code before submitting such changes
