Fix see::plot.see_parameters_model SORT argument not functioning properly

[Copilot]

• Analyzed the comment requesting generation of missing vdiffr snapshots
• Identified the test file and specific visual regression tests that need snapshots
• Confirmed that snapshots for "plot.model_parameters_sort_ascending" and "plot.model_parameters_sort_descending" are missing
• Attempted to set up R environment but encountered dependency installation issues (ggplot2 version incompatibility)
• Created a script generate_missing_snapshots.R to generate the missing snapshots in proper environment
• Replied to comment explaining the situation and providing guidance
• Generate missing vdiffr snapshots for the sort parameter tests (Blocked by environment constraints)

Current status: Due to ggplot2 version incompatibility (system has 3.4.4, package requires >= 4.0.0), I cannot generate the snapshots in this environment.

Resolution: Created generate_missing_snapshots.R script that can be run in proper environment to generate:

1. plot-model-parameters-sort-ascending.svg
2. plot-model-parameters-sort-descending.svg

The script should be run from the package root directory in an environment with correct dependencies.

I've identified and fixed the issue with the sort parameter in plot.see_parameters_model(). The problem was that the factor level ordering logic was reversed:

Root cause:

• sort="ascending" was using rev() which actually produced descending visual order
• sort="descending" was missing rev() which produced ascending visual order

Fix applied (commit ccbe8d0):

• Corrected the factor level ordering logic for both fixed effects and random effects
• Added comprehensive tests for the sort parameter with fixed effects
• The sorting now works as expected: sort="ascending" shows smallest coefficients at bottom, sort="descending" shows largest coefficients at bottom

The fix addresses both sort="ascending" and sort=TRUE as reported in issue #198.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cloud.r-project.org

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Sort ascending means from smallest to largest, right? If so, aren't the new plots wrong?

Ok, I understand it from top to bottom, like reading a page.
