Bug: `formatter.log=True` not respected in `ax.format`

[syrte]

Description
When uplt.rc["formatter.log"] = True, log formatting is correctly applied via ax.loglog(), ax.semilogx() etc, but ignored when setting the scale via ax.format().

Minimal Reproducible Example

import ultraplot as uplt
import numpy as np

uplt.rc["formatter.log"] = True
fig, ax = uplt.subplots()

# Applied correctly
ax.semilogx(np.linspace(1, 100)) 

# Applied incorrectly (remains scalar)
ax.format(yscale='log') 

uplt: 1.66.0
mpl: 3.10.8

Expected Behavior
Both axes should display labels in log format.

Actual Behavior
Only the axis initialized via semilogx uses log formatting. The axis set via ax.format(yscale='log') uses standard scalar labels.
