Migrate config to cameleer.server.* naming convention

Move all configuration properties under the cameleer.server.* namespace
with all-lowercase dot-separated names and mechanical env var mapping
(dots→underscores, uppercase). This aligns with the agent's convention
(cameleer.agent.*) and establishes a predictable pattern across all
components.

Changes:
- Move 6 config prefixes under cameleer.server.*: agent-registry,
  ingestion, security, license, clickhouse, and cameleer.tenant/runtime/indexer
- Rename all kebab-case properties to concatenated lowercase
  (e.g., bootstrap-token → bootstraptoken, jar-storage-path → jarstoragepath)
- Update all env vars to CAMELEER_SERVER_* mechanical mapping
- Fix container-cpu-request/container-cpu-shares mismatch bug
- Remove displayName from AgentRegistrationRequest (redundant with instanceId)
- Update agent container env vars to CAMELEER_AGENT_* convention
- Update K8s manifests and CI workflow for new env var names
- Update CLAUDE.md, HOWTO.md, SERVER-CAPABILITIES.md documentation
