feat: add OTLP log exporter

[leoparente]

This pull request adds support for exporting logs from the agent to an OTLP (OpenTelemetry Protocol) endpoint via gRPC, enabling better observability and integration with telemetry systems. It introduces a new telemetry logging module, updates configuration to allow enabling OTLP log export, and ensures proper lifecycle management of the OTLP exporter. Additionally, it updates dependencies to include OpenTelemetry packages and fixes a minor typo in the configuration struct.

OTLP Telemetry Logging Integration:

• Added a new telemetry package with logs.go and logs_test.go, implementing an OTLP log exporter for slog and providing unit tests for endpoint normalization and exporter creation. [1] [2]
• Integrated OTLP log exporter initialization and shutdown in the agent lifecycle (agent.go), including safe shutdown on backend restart or agent stop, and conditional activation based on configuration. [1] [2] [3] [4] [5] [6]

Configuration Changes:

• Added a new TelemetryLogs boolean field to the agent configuration to control whether OTLP log export is enabled.
• Fixed a typo in the configuration struct: renamed SecretsManger to SecretsManager. [1] [2]

Dependency Updates:

• Added OpenTelemetry and related packages to go.mod to support OTLP log export. [1] [2] [3] [4]
• Updated existing dependencies to newer versions for improved compatibility and security. [1] [2] [3]
