feat: add Apple M2/M3/M4 chip TDP values to cpu_power.csv

Fixes #758 - Apple Silicon chips from M2 onwards were not recognized
by CodeCarbon's TDP lookup table, causing users to fall back to a
constant default power estimate instead of a real measurement.

Added TDP entries for:
- Apple M2, M2 Pro, M2 Max, M2 Ultra
- Apple M3, M3 Pro, M3 Max, M3 Ultra
- Apple M4, M4 Pro, M4 Max, M4 Ultra

Added unit tests to verify correct TDP lookup for all new chip variants.
