A calmer batch page

The batch page is rebuilt around one path: add photos, run the analysis, download the CSV. A single button always shows the next step.

Switch between a list with the full texts and a grid of photos; in the grid, any photo opens in a side panel where you can read or correct its title, description and keywords.

Select photos across the whole batch, not just the visible page, and drop new photos anywhere on the page to upload them.
