Implement IVFFLAT probe settings and enhance post/user controllers

- Added a new method `set_ivfflat_probes!` in `ApplicationController` to configure IVFFLAT probe settings.
- Integrated `set_ivfflat_probes!` as a before action in `Domain::Fa::PostsController` and `Domain::Fa::UsersController` for the `show` action.
- Updated `set_domain_fa_post` method to include the `response` association in the post query.
- Increased the limit of similar posts displayed from 5 to 20 and included the creator's avatar in the post includes for better data retrieval.
