Lower numpy minimum version from 2.3.1 to 1.25.2

[ryanhill1]

Summary

• Lowers the numpy lower bound from >=2.3.1 to >=1.25.2
• The codebase only uses basic numpy APIs (array creation, linalg, FFT, trig) available since ~1.13
• The practical floor of 1.25.2 is dictated by scipy>=1.16.0's own numpy requirement and Python >=3.11 compatibility

Test plan

• Verify tests pass with numpy 1.25.2 installed
• Verify tests pass with latest numpy
