fix(dgw): resolve sspi dependency conflict by updating IronRDP to 0.7

[Copilot]

• Investigate CI errors
• Fix dependency conflicts
• Update IronRDP dependencies to fix sspi 0.16.1 incompatibility
• Adapt code to IronRDP API changes
• Verify gateway builds successfully
• Run cargo format
• Use into_gcc_blocks() to avoid clone
• Fix agent build (blocked by upstream IronRDP issue)

Summary

Fixed the CI build failure caused by sspi 0.16.1 dependency conflict by updating IronRDP dependencies and adapting to API changes. Applied code formatting and optimized gcc_blocks handling to avoid unnecessary cloning.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Run cargo format

@copilot Run cargo format

Formatted the code with cargo +nightly fmt --all in commit a3d461f.

[CBenoit]

@copilot See if you can use into_gcc_blocks() and remove the clone()

[Copilot]

Changed to use into_gcc_blocks() instead of gcc_blocks().clone() in commit a5effe3. This avoids the unnecessary clone by consuming the value.
