fix(contracts): drop unused project file search query exports

[waleedlatif1]

Summary

• feat(project-files): add rendered delivery and indexed search #9017 exported v2SearchProjectFileContentQuerySchema and V2SearchProjectFileContentQuery, but nothing outside the file imports them, so check:unused-exports fails on staging and on every PR rebased onto it
• The schema stays module-local (the contract still uses it); the unused type alias and its zod type import are removed

Type of Change

• Bug fix

Testing

• biome check on the file; CI's check:unused-exports is the gate
