Remove manual support triage fields

[ChiragAgg5k]

Summary

• remove manual category, topic, and severity controls from the support wizard
• submit only ticket content and account/project context so backend triage is authoritative
• simplify support wizard state shape

Testing

• bunx prettier --check src/routes/(console)/supportWizard.svelte src/routes/(console)/wizard/support/store.ts
• bunx eslint src/routes/(console)/supportWizard.svelte src/routes/(console)/wizard/support/store.ts
• bun run check (fails on existing unrelated SDK/model type errors; no diagnostics for changed support files when filtered)

Greptile Summary

This PR removes the manual category, topic, and severity controls from the support wizard, delegating triage entirely to the backend. The store shape is simplified by dropping category and topic, and message/subject are now nullable.

• The SupportData type drops category and topic, and relaxes message/subject to string | null so the store can represent a truly empty initial state.
• handleSubmit uses ?? '' to safely coerce null values before appending to FormData, and no longer constructs or sends the categoryTopicTag.
• The onDestroy reset omits the project key (while resetData includes project: null), leaving the property as undefined after unmount — harmless because project is optional and the ?? '' fallback in handleSubmit covers undefined too.

Confidence Score: 5/5

Safe to merge — the change removes UI-only fields and does not alter the core submission flow in any breaking way.

The diff is a straightforward deletion of category/topic fields with no new logic introduced. Null coalescing guards are in place for the nullable fields before they reach FormData, and the required form validation prevents empty submissions. No data is dropped that the backend depended on (it now owns triage), and the cleanup is symmetric across the store type, component state, and submit handler.

No files require special attention.
