## Backend: Timestamp Config for Client Defaults

Refs #286 — implements backend scope from the [final
spec](https://github.com/Kpa-clawbot/CoreScope/issues/286#issuecomment-4158891089).

### What changed

**Config struct (`cmd/server/config.go`)**
- Added `TimestampConfig` struct with `defaultMode`, `timezone`,
`formatPreset`, `customFormat`, `allowCustomFormat`
- Added `Timestamps *TimestampConfig` to main `Config` struct
- Normalization method: invalid values fall back to safe defaults
(`ago`/`local`/`iso`)

**Startup warnings (`cmd/server/main.go`)**
- Missing timestamps section: `[config] timestamps not configured —
using defaults (ago/local/iso)`
- Invalid values logged with what was normalized

**API endpoint (`cmd/server/routes.go`)**
- Timestamp config included in `GET /api/config/client` response via
`ClientConfigResponse`
- Frontend reads server defaults from this endpoint

**Config example (`config.example.json`)**
- Added `timestamps` section with documented defaults

### Tests (`cmd/server/`)
- Config loads with timestamps section
- Config loads without timestamps section (defaults applied)
- Invalid values are normalized
- `/api/config/client` returns timestamp config

### Validation
- `cd cmd/server && go test ./...` ✅
