FEATURE: First iteration of nested replies (#38888)
### Super high level description:
Adds a nested/threaded view for Discourse topics, allowing posts to be
displayed as an indented reply tree instead of the default flat
chronological stream.

  Backend:
- New /n/:slug/:topic_id routes serving roots, children (paginated), and
context (ancestor chain) endpoints
- TreeLoader recursively fetches reply trees with configurable max
depth, Sort supports top/new/old ordering
- NestedViewPostStat caches per-post reply counts (direct + total
descendants, whisper-aware) with a backfill job for existing data
  - NestedTopic model tracks per-topic opt-in and pinned post

  Frontend:
- Recursive <NestedPost> / <NestedPostChildren> components with
lazy-load expansion, cloaking, and scroll tracking
- NestedViewCache service preserves expansion state and scroll position
across back/forward navigation (15 entries, 10min TTL)
- Context view for deep-linking to a specific post with its ancestor
chain
  - Floating actions bar, sort selector, real-time MessageBus updates

Site settings (hidden): nested_replies_enabled, nested_replies_default,
nested_replies_default_sort, nested_replies_max_depth,
nested_replies_cap_nesting_depth, nested_replies_toggle_mode_groups,
plus a per-category default override.
