fix(ui): align Bulk Import detail actions with design

[Gordex2014]

Summary

• Replace the manifests table with headerless rows that preserve the full URL while ellipsizing it visually.
• Keep Submit visible on each row and move row-specific Abort and Remove actions into an accessible overflow menu.
• Replace the removed Submit All control with a working Most recent and Oldest sort menu.
• Use the shared menu, button, and dialog patterns from the UI instead of page-specific control geometry.
• Align Edit, Delete, Abort, and Complete with the approved detail composition and add a working Edit Submission dialog.
• Remove the extra card around the manifests collection. The section now uses the design's divider while each manifest keeps its own row boundary.
• Enforce submission and manifest action eligibility in rendered controls and direct POST handlers.
• Abort submitted manifests through a replace-only Bulk Submit kickoff without adding an empty replacement manifest.

State behavior

• Unsent manifests can be submitted but not aborted.
• Accepted manifests can be aborted but cannot be submitted again.
• Aborted manifests remain visible. Submit and Abort are disabled while Remove remains available.
• Failed submission attempts remain retryable.
• Completed and stopped submissions disable protocol actions while keeping local Edit, Delete, and Remove operations.
• Submission Log records attempts, recipient responses, polling progress, terminal state changes, replacements, and aborts. The persisted log keeps the latest 100 entries.

Compatibility

• Inherits the canonical button geometry introduced by fix(ui): unify the button size scale app-wide #744 without changing the global button scale.
• Retains the public empty-manifest compatibility endpoint.
• Leaves Bulk Export and ui: Bulk Export create form and job list do not match the design #735 unchanged.
• Keeps JavaScript-disabled create, add, remove, and menu navigation flows.
• Settings-store concurrency behavior remains non-transactional and unchanged by this PR.

Validation

• cargo fmt --all -- --check
• git diff --check
• cargo test -p helios-ui
  • 97 unit tests passed.
  • 29 Bulk Import HTTP tests passed.
  • All remaining helios-ui integration suites passed.
