Always show workflow editor close button (#10387)

[SagarSDagdu]

Description

Fixes #10387 — the "x" close button on the workflow/alias editor pane is currently hidden until the header is hovered, which makes dismissal hard to discover. Users may attempt to close the editor via the vertical tabs "x" instead, which closes the entire session.

This change sets always_show_icons = true on the standard header options returned by WorkflowView::render_header_content, so the pane's close button stays persistently visible — matching the pattern already used by network_log_view and ai/execution_profiles/editor.

Single-file change in app/src/workflows/workflow_view.rs.

Testing

• Built and ran Warp locally; opened a new personal workflow and confirmed the close button in the top-right of the editor pane is visible without hovering the header.
• Ran cargo fmt and cargo clippy -p warp --bin warp-oss --all-targets (clean).

No automated test added: similar UX-flag fixes elsewhere in the codebase (network_log_view.rs, ai/execution_profiles/editor/mod.rs) toggle always_show_icons without dedicated tests, since the change is a single render-time boolean and asserting on rendered header visibility would require new test scaffolding (a HeaderRenderContext test fixture and a WorkflowView singleton-soup setup) for limited additional confidence.

Thanks for the fix! We might consider making always showing icons the default (maybe we should do this for warp drive notebooks and env vars as well), but okay to leave out of scope here

@seemeroland
The Warp CI / Run Windows tests is flaky.
I have merged the latest upstream master, please re-trigger the workflows and lets hope this time it passes 🤞🏻
