Remove skipped tests and unreachable RPC methods (bd-212, bd-213)

bd-212: Delete 3 permanently skipped test functions (~150 LOC)
- TestImportDependencyUpdates (import_collision_test.go)
- TestImportChainDependencies (import_collision_test.go)
- TestUpdateDependencyReferences (collision_test.go)

bd-213: Remove 4 unreachable RPC methods (~80 LOC)
- Server.GetLastImportTime
- Server.SetLastImportTime
- Server.findJSONLPath
- Client.Import

All tests pass. Phase 1 dead code cleanup continues.
