Summary:
- Add support for exporting master logs to third-party sinks via the unified telemetry export API.
- Refactor so a new log/telemetry type touches only 2-3 files, not the whole task workflow:
  - `TelemetryConfig.section()/diff()/hasAnyConfig()` derive from it ---> new type = config model + one ExportType entry + its `OtelCollectorConfigGenerator` receiver.
  - `OtelCollectorUtil.getCurrentTelemetryConfig` resolves every section generically (table-first, per-section `userIntent` fallback, table-only types like master logs unchanged).
  - `ExportType.requiresDbRestart` drives the collector-only `NON_RESTART` fast path generically.
  - `MasterLogConfig/MasterLogLevel`, `UniverseServerLogsExporterConfig`, `MasterLogsTelemetrySpec` v2 schema, master filelog receiver (configurable min level + noise drop ratio), `ManageOtelCollector` `yb-master` systemd probe.

- Binary and systemD unit gets installed in both master and tserver nodes in case of dedicated master mode. Exports logs are from master node alone since tserver master log files are not populated
