✨ Refactor components and models:

- 🔥 Removed deprecated `placeholder-pattern` component.
- 🧹 Simplified and cleaned up Blade views by removing unused comments and sections.
- 🗂️ Extracted `SetsCreatedBy` concern for DRY and reused it across models.
- 🔧 Consolidated configuration for Horizon `authorized_nostr_keys`.
- 🧪 Migrated media conversion to use new Spatie enums for clarity.
- ♻️ Replaced repetitive link rendering with dynamic rendering in meetups and services views.
