This pull request updates the MicroHack Sovereign Cloud infrastructure setup to clarify event preparation instructions, improve cost control tracking, and ensure consistent tagging for resources. The changes streamline hosted vs. manual event setup, add or propagate CostControl: Ignore tags to relevant resources, and update documentation to reflect new resource paths and cost guidance.

Event Preparation and Documentation Updates:

• Clarified event preparation instructions in Readme.md to distinguish between Microsoft-hosted and manual setups, referencing the appropriate runbooks and emphasizing LocalBox preparation and validation.
• Updated cost guidance for LocalBox in Readme.md, specifying per-subscription costs, hosted event scheduling, and linking to hosted-event budget guidance.
• Corrected script paths in documentation to refer to the new manual-setup directory for quota and RBAC scripts. [1] [2]

Resource Tagging for Cost Control:

• Added CostControl: Ignore tags to all major lab and LocalBox resources in deployment scripts (deploy-lab.ps1, deploy-localbox.ps1, shared-deploy-lab.ps1) and Bicep templates to improve cost tracking and exemption management. [1] [2] [3] [4] [5] [6] [7]
• Ensured that reused LocalBox deployments have their VM resources updated with the CostControl: Ignore tag if missing.

Resource Provider Registration:

• Added Microsoft.EdgeMarketplace to the list of required resource providers for lab automation.
