fix: fixes across dockercompose casting

[Nageshbansal]

Fixes

• Fix enricher MetaStore port from 9000 to 5432 (PostgreSQL) and ingester port from 9000 to 4317 (OTLP
  gRPC)
• Add env var support for all services from Spec.Env (populated by moldings) instead of hardcoding
• Use enricher-provided SIGNOZ_OTEL_COLLECTOR_CLICKHOUSE_DSN env for ingester and migrator instead of
  hardcoded DSN in command args
• Add opamp.yaml and functions.yaml config mounts (generated by moldings but previously not mounted)
• Update ingester command to use migrate sync check + opamp config pattern
• Update migrator command to use ready && bootstrap && sync up && async up pattern
• Add restart policies for ingester and signoz services
• Fix telemetrystore config template to use YAML list for replicas (avoids duplicate key error with
  replicas > 1) (mapping was broken during this feat(docker): file generation for docker compose #27 )
• Fix telemetrystore molding getData replica count: use Replicas + 1 to match compose template semantics
• Align config output paths to include component Kind (e.g. telemetrykeeper/clickhousekeeper/)
