feat: read document pickers from DEMI

[danieltruong]

Document edit now works on DEMI rows, and the two document pickers read DEMI's native /documents.

Document edit:

• DEMI rows are mapped before the form uses them. The Eagle id, the Eagle project id and the list ids go into the fields the form expects. Without this, a save would have written list labels into the type fields.
• Update, publish and unpublish go to eagle-api with the Eagle document id.
• If a selected row has no Eagle id, the Save buttons are hidden and a warning explains why.
• Fixed along the way: togglePublish built its request inside the per-row loop.

Pickers:

• The comment period picker sends the DEMI project id. If the stored project has no DEMI id, it looks it up first. The Type and Milestone columns no longer sort.
• The notification picker sends the notification id as project. Status reads isPublished. The Author and Status columns no longer sort.
• Both pickers leave out rows that exist only in DEMI, because they cannot be attached through eagle-api.

Known gap: the comment period picker used to send documentSource, which DEMI does not accept yet. A follow-up adds it once DEMI supports it.

Uploads are unchanged.

Tests: edit saves by Eagle id for both row shapes, hidden Save for rows with no Eagle id, the row mapper, and the query each picker sends.
