fix: harden recording creation, share playback, and desktop reliability

[richiemcilroy]

A failed upload-progress insert could leave a newly created recording without its progress row. The affected web, desktop, and mobile creation paths now commit both rows in one transaction. A media error on an initial signed MP4 URL triggers one authorized refresh; playback restores the playhead and resumes if it was active. Abandoned editor construction aborts segment loading. Windows builds compile only the memory-pressure states they can sample. GPUI asset validation now sees the Windows caption controls and embeds only icons still used by its windows; its generated lockfile includes the dependency required by editor cancellation.

Validation: 223 focused and adjacent web tests passed; the editor crate checked and 184 Rust tests passed (3 ignored). The utils crate checked, 12 export-resource tests passed (1 ignored), and strict local Clippy passed. The GPUI crate checked with locked dependencies and all four focused asset tests passed. Scoped Biome, Cargo formatting, backend TypeScript, and isolated-diff whitespace checks passed. Exact-head CI passed all required checks, including Linux, macOS, and Windows desktop builds and GPUI tests, strict Clippy, typecheck, Biome, native sync, and recording recovery. Browser playback and Windows native editor interaction were unavailable locally.

Confidence Score: 5/5

The PR appears safe to merge, with no outstanding actionable failures identified in the current changes.

Summary

This PR makes recording and upload-progress creation atomic across web, desktop, mobile, and backend paths; refreshes expired signed playback sources while preserving playback state; cancels abandoned editor segment loading; corrects platform-specific memory-pressure compilation; and aligns GPUI assets and lockfiles.

• Creates video and initial upload rows in the same database transaction.
• Adds one-time signed-source refresh with playhead and playing-state restoration.
• Aborts segment-loading tasks when editor construction is abandoned.
• Restricts memory-pressure variants to supported platforms.
• Updates GPUI asset validation and generated dependency locks.
