feat(tui): add SLA reporting view

Full-screen SLA report accessible via [s] from detail panel.
Computes uptime%, downtime, outage count, longest outage, MTTR,
and MTBF from state_changes table. Includes daily breakdown with
bar chart, switchable time periods (24h/7d/30d/90d), and
scrollable viewport. LATE/STALE treated as UP for SLA purposes.

-### Running behind a reverse proxy
-
-By default uptop ignores the `X-Forwarded-For` header and rate-limits by the direct connection address — so a client can't spoof the header to bypass limits. If uptop sits behind a reverse proxy (nginx, Caddy, Cloudflare, an ALB), set `UPTOP_TRUSTED_PROXIES` to the proxy's address(es) so the real client IP is used instead:
-
-    # single nginx/Caddy on the same host
-    UPTOP_TRUSTED_PROXIES=127.0.0.1
-
-    # a proxy subnet, or Cloudflare ranges
-    UPTOP_TRUSTED_PROXIES=10.0.0.0/8,172.16.0.0/12
-
-Only requests whose immediate peer is in this list have their `X-Forwarded-For` honored (right-most non-trusted hop wins). Bare IPs are treated as single hosts; invalid entries are warned about and skipped. Leave it unset if uptop is exposed directly.

-### Data retention
-
-uptop prunes its own history in the background — no external cleanup jobs needed:
-
-| Data | Kept |
-|---|---|
-| Check history | newest 1,000 checks per monitor |
-| State changes (UP/DOWN transitions) | newest 5,000 per monitor |
-| Logs | newest 200 entries |
-| Maintenance windows | 7 days after they end (configurable) |
-
-Sparklines, uptime percentages, and SLA reports are computed from these windows, so very long-horizon stats aren't retained. Export to Prometheus via `/metrics` if you need unlimited history.
-
 ## Clustering
 
 uptop supports three modes: **leader** (default single node), **follower** (HA failover — takes over if the leader goes down), and **probe** (stateless distributed checks from multiple regions).

 Apply is idempotent. Run it twice with the same file, second run changes nothing.
 
-Apply is **not atomic** — items are written one at a time, so an error mid-apply (bad value, lost DB connection, ctrl-C) leaves the items already written in place. That's safe to recover from: apply diffs against the database by name, so fix the issue and run it again — it converges the rest. Just don't run two applies against the same database at once.

-## Backups and secrets
-
-`uptop export` writes alert credentials (SMTP passwords, API tokens, webhook URLs) into the YAML in clear text — that's what makes the file restorable. Treat it like a secrets file.
-
-The HTTP export endpoint redacts those same fields **by default**:
-
-```bash
-# secrets show as ***REDACTED*** — fine for sharing or review
-curl -H "X-Uptop-Secret: your-secret" \
-  "http://localhost:8080/api/backup/export"
-
-# full backup you can actually restore from
-curl -H "X-Uptop-Secret: your-secret" \
-  "http://localhost:8080/api/backup/export?redact_secrets=false"
-```
-
-Restoring a redacted export imports the literal string `***REDACTED***` as your credentials. For real backups, pass `redact_secrets=false` or run `uptop export` on the host.
