Louis King 3810e029ce feat: HTTP Cache-Control, dashboard TTL bump, and route event-hash dedup
Bundles four independent improvements to API caching and route evaluator
accuracy that all touch the same files in the cache/routes stack.

## HTTP Cache-Control headers (api_cache_control_enabled)

The API now emits HTTP Cache-Control on every /api/v1/* response and
handles ETag / If-None-Match -> 304 Not Modified on @cached endpoints.

- @cached GETs: private, max-age=<redis_ttl> + strong SHA-256 ETag.
  Matching If-None-Match returns 304 with empty body.
- Uncached GETs under /api/v1/*: private, max-age=0, must-revalidate.
- POST/PUT/DELETE/PATCH and /health*: no-store.
- All private (several @cached endpoints are role-aware).
- @cached decorator stores new envelope {body, etag} in Redis; legacy
  bare-JSON entries still read (hashed on the fly) and auto-migrate on
  the next miss.
- X-Cache: HIT|MISS observability header is always emitted.
- Kill switch: API_CACHE_CONTROL_ENABLED (default true).

## Dashboard cache TTL bump (30s -> 300s)

REDIS_CACHE_TTL_DASHBOARD default raised from 30s to 300s. Covers all
/dashboard/* endpoints and /api/v1/routes/{id}/history. These return
trend/aggregation data where minute-level staleness is invisible but
every MISS costs seconds of SQL/aggregation. Also resolves reported
short-TTL behaviour on the per-route healthchart (which shares this
setting). Operators with explicit env var: unchanged. Old Redis entries
expire naturally within <=30s; no flush needed.

## Route recent-packets hop truncation

In the routes page expanded card, path hops are now truncated to
2 + ellipsis + 2 when length > 5, matching the packet-detail page
styling. Reuses the existing packets.hops_hidden i18n key as the
tooltip on the ellipsis badge.

## Route event-hash deduplication

A single advert/message/telemetry/trace retransmitted or flooded
through the mesh produces one RawPacket per on-air copy, each with a
fresh wire packet_hash. Counting those as distinct matches let a single
underlying event satisfy packet_count_threshold within seconds and
biased route health.

- Add nullable event_hash column to raw_packets and packet_path_hops
  (alembic 6b3430fd84f4). No backfill; legacy rows keep NULL and the
  evaluator falls back to wire packet_hash until they age out of
  window_hours.
- Subscriber denormalizes the structured event's event_hash onto the
  captured raw packet after handler dispatch.
- Route evaluator prefers event_hash when set, collapsing all
  receptions of the same underlying event into one match.
