fix(deps): update typescript-vue-apollo to v6 for codegen v8

typescript-vue-apollo 5.x fails plugin validation under @graphql-codegen/cli 8
("The path argument must be of type string"). 6.0.0 targets plugin-helpers 8.

typescript-operations v7 emits every schema type used in a document, so
running it in the same output as the typescript plugin produced a duplicate
Range declaration. Split codegen into schema.ts (typescript) and
operations.ts (operations, vue-apollo, fragment-matcher) with
importSchemaTypesFrom, matching the Shiny frontend layout, and import
Event, DanceHallDistance and Range from the schema file.

Lockfile regenerated in cypress/base:26.13.0 to keep Linux optional deps.
