fix(sap-demo-java): correct globalNoise schema to nested sections

Keploy's GlobalNoise is typed `map[string]map[string][]string` — two
levels of nesting. The committed keploy.yml instead used flat dotted
keys under `globalNoise.global` (e.g. `header.X-Correlation-Id: []`,
`body.correlationId: []`), which parse as a single string key with a
literal dot in it. Keploy then never matched those keys against the
(header, field) / (body, field) lookups during noise suppression, so
the curated noise block was silently a no-op.

Re-nest every entry: `header.X-Correlation-Id` becomes
`header: { X-Correlation-Id: [] }`, and all the `body.*` keys move
under a single `body:` parent. The actuator/health DataSource status
comment is preserved above `status: []`.
