This commit introduces a new `Problem` model, analogous to `Crop`, to allow users to track problems they have on their plantings (e.g., aphids on tomatoes). Key features: - A new `Problem` model that can be curated by admins (`problem_wranglers`). - Users can associate problems with their plantings and upload photos of the problems. - Aggregated problem information is displayed on the crop detail page (e.g., "Problems: aphids (27), blight (13)"). - Users can mention problems in posts (e.g., `[aphids](problem)`), which automatically links to the problem's page. - Admin functionality for reviewing and approving new problem suggestions. Resolves merge conflict in app/controllers/plantings_controller.rb
