## Summary
Fixes#19076
An attempt at fixing #19076 where the rule could change program behavior
by incorrectly converting from_float/from_decimal method calls to
constructor calls.
The fix implements argument validation using Ruff's existing type
inference system (`ResolvedPythonType`, `typing::is_int`,
`typing::is_float`) to determine when conversions are actually safe,
adds logic to detect invalid method calls (wrong argument counts,
incorrect keyword names) and suppress fixes for them, and changes the
default fix applicability from `Safe` to `Unsafe` with safe fixes only
offered when the argument type is known to be compatible and no
problematic keywords are used.
One uncertainty is whether the type inference catches all possible edge
cases in complex codebases, but the new approach is significantly more
conservative and safer than the previous implementation.
## Test Plan
I updated the existing test fixtures with edge cases from the issue and
manually verified behavior with temporary test files for
valid/unsafe/invalid scenarios.
