Second part of the post-beta audit fixes. Server change: the upload reject reason is also sent in an x-thoth-upload-error header, and one history label is reworded. Everything else is web-only.

Narrow windows

• At 760 px and below, the project list becomes a drawer opened from the top bar. Escape, an outside click or picking a project closes it, and focus returns to the button.
• The top bar stays on one line and folds its labels to icons with tooltips.
• At 320 and 390 px, no screen scrolls sideways in any of the five languages. Before, pages were 371–611 px wide.
• At 1100 px and below, the detail panel covers the whole conversation instead of half of the answer.
• Korean text wraps between words.
• Archived projects take one row each, with a menu.

Sources tab

• Connected sources are listed first. At 1440×900, the first card moved from 745 px to 237 px from the top.
• Choosing a file connects it right away with the local default scope ("shared in this project"). The scope can be changed from one expandable line. The hosted review site still asks.
• Files that cannot be uploaded are reported before sending, with the file name, the reason and the accepted formats, in five languages.
• Web sources show one line and a settings link until they are allowed.

Settings and history

• Project settings and computer settings are now two separate screens, with no item on both.
• Model fields say whose default they are. With no model connected, the screen shows one sentence and a link instead of disabled selects.
• Research history shows records first, has one refresh button, and shows the comparison card only after a choice.
• The new project screen keeps only the name field and one primary button.
• Providers are marked by a colour dot.
• First-run setup offers "connect later".

Validation

• axe reports 0 violations on 13–17 screens per batch.
• Mutation checks: 25, 24 and 21 per batch, all caught.
• QA scenarios Q-30–36, Q-60–63 and Q-80–86 pass in a browser.
• Not checked: narrow windows with a model connected, and a real 65 MB upload.
