fix: prevent duplicate prompts when using Templater in Capture choices

When Templater code with tp.system.prompt was used in Capture choices, the prompts
would appear twice and only the second response would be used in the note. This change:

- Processes Templater code only once during the initial formatting
- Prevents secondary processing of the same Templater code
- Ensures prompt responses are correctly captured on the first attempt

Fixes #533
