feat(telemetry): add new Telemetry service (OTel, Syslog, Fluent, Metrics, Traces) and unified ingestion pipeline 
- Add Telemetry service entrypoint
  - Telemetry/Index.ts: app bootstrap, routes mounting, infrastructure init and Telemetry SDK init.

- Unified queue + worker
  - Telemetry/Jobs/TelemetryIngest/ProcessTelemetry.ts: single worker that dispatches queued jobs to specific processors (logs, traces, metrics, syslog, fluent logs).
  - Telemetry/Services/Queue/TelemetryQueueService.ts: central queue API and job payload types.
  - Per-type Queue wrappers (LogsQueueService, MetricsQueueService, TracesQueueService, FluentLogsQueueService, SyslogQueueService).

- OpenTelemetry ingestion middleware and proto support
  - Telemetry/Middleware/OtelRequestMiddleware.ts: detect OTLP endpoint (logs/traces/metrics), decode protobuf bodies using protobufjs and set product type.
  - Telemetry/ProtoFiles/OTel/v1/*.proto: include common.proto, logs.proto, metrics.proto, resource.proto, traces.proto for OTLP v1 messages.

- Ingest services
  - Telemetry/Services/OtelLogsIngestService.ts: parse incoming OTLP logs, map attributes, convert timestamps, batch insert logs.
  - Telemetry/Services/OtelTracesIngestService.ts: parse OTLP traces, build span rows, extract exceptions, batch insert spans and exceptions, save telemetry exception summary.
  - Telemetry/Services/OtelMetricsIngestService.ts: parse OTLP metrics, normalize datapoints, batch insert metrics and index metric name -> service map.
  - Telemetry/Services/SyslogIngestService.ts: syslog ingestion endpoints, parser integration, map syslog fields to attributes and logs.
  - Telemetry/Services/FluentLogsIngestService.ts: ingest Fluentd style logs, normalize entries and insert into log backend.
  - Telemetry/Services/OtelIngestBaseService.ts: helpers to resolve service name from attributes/headers.

- Syslog parser and utilities
  - Telemetry/Utils/SyslogParser.ts: robust RFC5424 and RFC3164 parser, structured data extraction and sanitization.
  - Telemetry/Tests/Utils/SyslogParser.test.ts: unit tests for parser behavior.

- Telemetry exception utilities
  - Telemetry/Utils/Exception.ts: generate exception fingerprint and upsert telemetry exception status (saveOrUpdateTelemetryException).

- Queue & job integration
  - New integration with Common/Server/Infrastructure/Queue and QueueWorker, job id generation and telemetry job types.
  - Telemetry services add ingestion jobs instead of processing synchronously.

- Config, build and dev tooling
  - Add Telemetry/package.json, package-lock.json, tsconfig.json, nodemon.json, jest config.
  - New script configs and dependencies (protobufjs, ts-node, jest, nodemon, etc).

- Docker / environment updates
  - docker-compose.base.yml, docker-compose.dev.yml, docker-compose.yml: rename service from open-telemetry-ingest -> telemetry and wire TELEMETRY_* envs.
  - config.example.env: rename and consolidate environment variables (OPEN_TELEMETRY_* -> TELEMETRY_*, update hostnames and ports).
  - Tests/Scripts/status-check.sh: update ready-check target to telemetry/status/ready.

- Other
  - Telemetry/Services/Queue/*: export helpers and legacy-compatible job interface shims.
  - Memory cleanup and batching safeguards across ingest services.
  - Logging and capture spans added to key code paths.

BREAKING CHANGES / MIGRATION NOTES:
- Environment variables and docker service names changed:
  - Replace OPEN_TELEMETRY_... vars with TELEMETRY_... (PORT, HOSTNAME, CONCURRENCY, DISABLE_TELEMETRY, etc).
  - docker-compose entries moved from "open-telemetry-ingest" to "telemetry" and image name changed to oneuptime/telemetry.
  - Update any deployment automation and monitoring checks referencing the old service name or endpoints.
- Consumers: OTLP endpoints and behavior remain supported, but ingestion is now queued and processed asynchronously.

Testing / Running:
- Install deps in Telemetry/ (npm install) after syncing Common workspace.
- Run dev: npx nodemon (nodemon.json) or build & start using provided scripts.
- Run tests with jest (Telemetry test suite includes SyslogParser unit tests).

Files added/modified (high level):
- Added many files under Telemetry/: Index, Jobs, Middleware, ProtoFiles, Services, Utils, Tests, package and config artifacts.
- Modified docker-compose.* and config.example.env and status check script to use new TELEMETRY service/vars.
