fix(sdk): resolve getResource by requested type

[thorthelegend99]

Summary

• make SDK findFileById optionally type-aware using resource folder matching
• pass requested resource type from getResource into findFileById
• add regression test for duplicate id across different resource types (channel + service)
• add changeset for @eventcatalog/sdk

Why

When multiple resource types share an id, getService/getEvent-style calls could resolve the wrong resource because lookup was id-only.

Validation

• pnpm --filter @eventcatalog/sdk exec vitest run src/test/resources.test.ts
• pnpm --filter @eventcatalog/sdk exec vitest run src/test/services.test.ts -t "returns the given service id from EventCatalog and the latest version when no version is given"
