docs: add max_turns_to_send and evaluation_mode rule fields, move sampling_rate to rule level

[Madhuvod]

Summary

This PR documents two new guardrail rule fields (max_turns_to_send and evaluation_mode) across all guardrail documentation and example configurations, and removes sampling_rate from provider-level configuration blocks where it does not belong (it is a rule-level field, not a provider-level field).

Changes

• Removed sampling_rate from provider config examples and reference tables for AWS Bedrock Guardrails, Azure Content Safety, Gray Swan, Lakera Guard, and Microsoft Presidio — sampling_rate is a rule-level field and was incorrectly documented at the provider level
• Added max_turns_to_send and evaluation_mode to the guardrail rule field reference tables and example configurations across config.json, Helm, and enterprise guardrails docs
• Added stream_replay_event_interval_ms to the rule-level reference table in the config.json guide with a full description
• Updated the Kubernetes example values file to include max_turns_to_send, evaluation_mode, and stream_replay_event_interval_ms in the rule configuration

Type of change

• Bug fix
• Feature
• Refactor
• Documentation
• Chore/CI

Affected areas

• Core (Go)
• Transports (HTTP)
• Providers/Integrations
• Plugins
• UI (React)
• Docs

How to test

Review the rendered documentation to confirm:

• sampling_rate no longer appears in provider-level config blocks or reference tables
• max_turns_to_send, evaluation_mode, and stream_replay_event_interval_ms appear correctly in rule-level reference tables with accurate descriptions
• Example YAML/JSON snippets are syntactically valid and consistent across config.json and Helm guides

Breaking changes

• Yes
• No

Security considerations

None. This is a documentation-only change.

Checklist

• I read docs/contributing/README.md and followed the guidelines
• I added/updated tests where appropriate
• I updated documentation where needed
• I verified builds succeed (Go and UI)
• I verified the CI pipeline passes locally if applicable

📝 Walkthrough

Summary by CodeRabbit

• Documentation
  • Updated guardrail configuration guides with conversation-history controls, including maximum turns, evaluation mode, and streaming replay intervals.
  • Removed obsolete provider-level sampling-rate configuration references.
  • Added examples showing eight-turn history limits, per-turn evaluation, and 25 ms streaming replay intervals.
  • Updated the Kubernetes guardrail example to reflect the new rule settings.

Walkthrough

Guardrail JSON and Helm documentation removes deprecated provider-level sampling_rate settings. Rule documentation and the Kubernetes example add conversation-history limits, evaluation modes, and streaming replay intervals.
