fix(flow): match alert triggers by rule key or name

[gdemoni]

Summary

• Pass both the canonical alert rule key and display name to the flow dispatcher.
• Match trigger.alert_fired rule filters against either value while preserving case-insensitive substring and minimum-severity behavior.
• Keep the existing trigger payload compatible and add regression coverage for rule keys that differ from display names.

Fixes #410

Testing

• go test ./internal/manager/biz/flow ./internal/manager/biz/alert -count=1
• go vet ./internal/manager/biz/flow ./internal/manager/biz/alert
• go test ./... was run locally; unrelated Windows-specific tests require Unix tools, symlink/file permission support, or ONNX build constraints.

Hi maintainers! @singchia

It looks like the workflows for this PR are awaiting approval. When someone please approve them when convenient so the required checks can run? Thank you!

Hi @gdemoni, all three CI jobs have passed. The remaining blocker is required checklist: the rerun of the September 11 workflow failed with Missing required PR checklist item.

The current PR description already has the required checkbox checked, and I verified that it passes the checklist script locally. The rerun appears to be using the older event payload rather than the current description.

Could you please make a small edit to the PR description and save it, keeping the contribution-guide checkbox checked? This will trigger a fresh checklist run. Please do this from your account, since the workflow rejects description-edit events from anyone other than the PR author.

Hi @youzi-1122 , I’ve updated the PR description from my account while keeping the contribution-guide checkbox checked. All five code checks have passed, and the newly triggered required checklist workflow is now awaiting maintainer approval. Could you please approve it when convenient? Also, please let me know if anything else is needed before the PR can be reviewed and merged. Thank you!
