The bot_user method in the TeamBotInstallation model was previously using the `where(...).last` approach to fetch the BotUser, which could result in unnecessary database queries when called multiple times. This fix optimizes the method by replacing `where(...).last` with `find_by(id: ...)`, ensuring only a single query is executed per call. Additionally, a test has been added to verify that no additional queries are triggered when accessing the `bot_user` method multiple times on the same instance, ensuring that the optimized code works as expected and prevents potential N+1 query issues. Changes: - Replaced `where(...).last` with `find_by(id: ...)` in the `bot_user` method. - Added a test to verify that no extra queries are triggered when calling `bot_user`.

Description
The bot_user method in the TeamBotInstallation model was previously using the
where(...).lastapproach to fetch the BotUser, which could result in unnecessary database queries when called multiple times. This fix optimizes the method by replacingwhere(...).lastwithfind_by(id: ...), ensuring only a single query is executed per call.Changes:

How has this been tested?
A test has been added to verify that no additional queries are triggered when accessing the
bot_usermethod multiple times on the same instance, ensuring that the optimized code works as expected and prevents potential N+1 query issues.Checklist
