Traces type consolidation

[stephlow]

The rust and ts apis where quite a bit different in handling traces / spans, which made it hard to make the ingestion engine compatible without a lot of effort.
This PR aims to unify the rust api and the ts api by trimming down the unnesecerry stuff from both sides and consolidate the api's, both with their native impls, as it's currently the case

original slack discussion

ts

• Moves the Otel related types to the shared package
• Introduce response specific types
• Removed raw_payload field
• Rename parsed_payload to inner
• Provide a type inferred schema, using drizzle, for the json field inner (prev. parsed_payload)
• Loads of imports moved to packages/types

rust

• Removes ts_compat models that were used to bridge the gap, introduced in Implement TypeScript API compatible AttributeMap #199
• Rename paths to follow the ts api pattern /api/traces -> /v1/traces
• Serde serializion adjustements to make the AttributeMap compatible with the ts api
• Updated the TraceSummary to reflect the ts api
