Scanner rpc active

[r2dedios]

Summary

This PR merges the scanner-rpc-active branch into release-0.6, bringing the scanner redesign and a series of console and backend improvements:

Scanner Redesign

• Redesign scanner as a long-running gRPC service replacing the previous CronJob-based approach
• Add API readiness check, account seeding, and billing optimization
• New proto definitions and generated gRPC code for scanner service

Events & Actions Backend

• Rename triggered_by to requester across the entire stack (DB schema, Go models, DTOs, repositories, services, handlers, API contracts) for consistent naming
• Persist requester and description in the schedule table so the Agent preserves requester identity through the polling cycle
• Add schedule_id, resource_name, and account_name to event views for richer audit data
• Add Account resource type to the audit event system
• Handle NULL columns in system events and schedule models

Console — Audit Logs & Scheduler

• Redesign Audit Logs table with operation labels, resource badges, status labels, and linked schedule actions
• Redesign Scheduler table: add ID, Requester, Description columns; merge Time/Cron into unified Schedule column; Yes/No enabled labels
• Add cronstrue for human-readable cron expressions

Console — Account Details

• Add "Actions" dropdown with Scan option to Account Details page
• Confirmation modal before triggering account scan
• Creates an InstantAction targeting the specific account

Console — General Improvements

• Add ResourceBadge and ResourceLabel components with styled action labels
• Unify Target column rendering across tables
• Align Recent Events (Overview) table with Audit Logs rendering (same labels, badges, timestamps)
• Add error handling to action creation API calls in both Account and Cluster dropdowns
• Replace ModalPowerManagement with ModalCreateAction
• Fix resource path resolution and handle empty resourceId

Infrastructure

• Update Helm templates and compose files for scanner service
• Pin container image and deployment configuration

Test plan

• make go-unit-tests — all pass
• make console-lint — 0 errors
• Manual: verify Audit Logs table renders with operation labels, resource badges, and status labels
• Manual: verify Scheduler table shows ID, Requester, Description, unified Schedule column
• Manual: verify Account Details → Actions → Scan creates an instant scan action
• Manual: verify Overview Recent Events matches Audit Logs rendering
• Manual: verify requester is populated in Audit Logs after Agent processes actions
