feat: add Jira heartbeat management components

[felixgateru]

Resolves #4893

What changed

Adds four Jira Service Management (JSM) Operations workflow components:

• Create Heartbeat — register a new heartbeat monitor (interval, alerts, etc.)
• Ping Heartbeat — report liveness for an existing heartbeat
• Update Heartbeat — change heartbeat settings (optional fields via toggles)
• Delete Heartbeat — remove a heartbeat from a team

Why

Enable Superplane workflow to manage Jira Heartbeats that detects when scheduled jobs, cron tasks, or automated systems stop reporting in. If a heartbeat is not pinged within its expected interval, Jira Service Management raises an alert.

How

Backend:

Implemented new client methods in pkg/integrations/jira/client.go for heartbeat endpoints.
Registered actions in pkg/integrations/jira/jira.go and updated token permission guidance.
Added tests

Frontend:

Added Jira workflow v2 mappers
Registered mappers and event states in web_src/src/pages/workflowv2/mappers/jira/index.ts
Added mapper specs
