deps: repoint lance-graph git deps from the feature branch to main

[claude]

What

AdaWorldAPI/lance-graph#1206 (the Axis-4 WideFieldMask widening) is merged, so main now carries the widened ClassRbac::field_mask that ogar-auth and ogar-rbac were pinned to a feature branch to reach.

-lance-graph-contract = { git = "…/lance-graph", branch = "claude/patient-identity-architecture-r8lhi5" }
+lance-graph-contract = { git = "…/lance-graph", branch = "main" }
-lance-graph-rbac     = { git = "…/lance-graph", branch = "claude/patient-identity-architecture-r8lhi5" }
+lance-graph-rbac     = { git = "…/lance-graph", branch = "main" }

Why this is not cosmetic

Pointing at a feature branch was correct only while that branch was the sole place the widened trait existed — main would not have compiled. Once #301 merged, though, OGAR main was depending on a branch that can be deleted the moment its PR merges, at which point main stops resolving its dependencies. This closes that window.

Three lines, two files, no code change.

Verified

• Resolves to main#2918421.
• ogar-auth 19/19, ogar-rbac 7/7.
• cargo fmt --check and cargo clippy -D warnings clean.

Branch restarted from main rather than stacked, since its predecessor (#301) is already merged.
