V55: Standalone Comments Module

Creates polymorphic comments tables decoupled from the Posts module.
Comments can be attached to any resource type via `resource_type` + `resource_id`.

## Tables

- `phoenix_kit_comments` — threaded comments with polymorphic resource association
- `phoenix_kit_comments_likes` — comment like tracking
- `phoenix_kit_comments_dislikes` — comment dislike tracking

## Design

- Polymorphic: `resource_type` (varchar) + `resource_id` (uuid), no FK constraints
- Self-referencing `parent_id` for unlimited threading depth
- Counter caches for `like_count` and `dislike_count`
- Status-based moderation (published/hidden/deleted/pending)
- Old `phoenix_kit_post_comments` tables remain untouched
