Provide a fieldable way to score sessions

There was a thread that inspired this issue in Drupal slack: https://drupal.slack.com/archives/C03KZ3BETNH/p1732954534050609

The MR uses a webform to rate sessions, with only an entity reference field and a Likert field for the actual scoring. The latter captures the actual ratings, and can be quickly customized for whatever evaluation rubric a particular camp may want. Note that proper aggregation of the Likert field (for the sake of ordering based on average score) requires applying the patch from ✨ Add an "average" formatter for Likert elements Active .

Merged this into a new 1.1.x branch. Additional refinements are likely needed, but we can deal with those in other issues.
