Problem description

Forms with different expressions, for example:

• city=${city} and age=${age}
• age < 18
• starts-with(${fname}, ${start})

Are much slower during filtering or opening draft / finalized form.
On my Android 14 device - Galaxy M23, regular 100k entity filter form filtering and opening draft / finalized form takes about 0.5 second, but on forms with expressions filtering takes ~5 seconds and opening draft / finalized form takes ~7 seconds

Steps to reproduce the problem

1. Scan project "perf" from https://staging.getodk.cloud/#/projects/103/app-users
2. Go to start new form
3. Open Entities 100k and expression form
4. In first question type "7" and swipe to the next question
5. In second question type "7" and swipe to the next question
6. Save form as draft
7. Go to drafts and open previously saved form
8. Compare performance to 100k Entity filter form
9. Repeat steps 1-8 excluding step 5. for 100k entities >< expression form and 100k entities starts with expression form
