but_api macro: Auto export

[estib-vega]

Automagically export the ‘complex types’ referenced in the function
signatures.

• Introduce but_transport, substituting most of the necessary
  boilerplate.
• Replace a bunch of boiler-plate code for used for transport

[Copilot]

Pull request overview

This PR introduces a new #[but_transport] attribute macro to standardize/auto-generate transport DTO boilerplate (serde + schemars + SDK registration), and updates many Rust DTOs across crates to use it. It also tightens schema export behavior by enforcing transport-marker usage and improving schema collection/duplicate handling for TypeScript generation.

Changes:

• Added #[but_api_macros::but_transport] and applied it broadly to transport structs/enums to reduce repeated serde/schemars/SDK-registration boilerplate.
• Updated #[but_api] macro to collect/enforce exported transport types via a new but_schemars::SdkTransportType marker.
• Improved but-ts schema collection to allow identical duplicate registrations while rejecting incompatible duplicates; updated generated SDK typings accordingly.

crates/gitbutler-project/src/api.rs:18

• #[but_transport(register = false)] defaults to #[serde(rename_all = "camelCase")], which renames these computed fields from gerrit_mode / forge_review_template_path to gerritMode / forgeReviewTemplatePath in JSON and in the generated SDK typings. The desktop app still expects the original snake_case keys (e.g. projectsService.getProject(...).response?.gerrit_mode). If the legacy API is meant to remain snake_case, pass rename_all = "snake_case" here (and keep #[serde(default)] behavior), or update all consumers in the same change set to use the camelCase keys.
