Checklist

Tests for the changes have been added (if needed)
Docs have been reviewed and added / updated
Lint (black rocketpy/ tests/) has passed locally
All tests (pytest tests -m slow --runslow) have passed locally
CHANGELOG.md has been updated (if relevant)

Current behavior

Rocket.power_off_drag and Rocket.power_on_drag had been changed to store raw user input, which broke backward compatibility because these public attributes were historically Function objects. This also created type inconsistency depending on construction path (for example, from_dict could still pass a Function).

New behavior

Restores Rocket.power_off_drag and Rocket.power_on_drag as Mach-only Function objects (aliasing power_off_drag_by_mach and power_on_drag_by_mach) to preserve the public API.
Preserves original user-provided drag inputs via new attributes:
- power_off_drag_input
- power_on_drag_input
Updates related docstrings in:
- rocketpy/rocket/rocket.py
- rocketpy/rocket/point_mass_rocket.py
Adds an Unreleased → Fixed changelog entry in CHANGELOG.md for this PR.
