feat: PDF sources: read, take notes and cards from pages, deadlines PDFs live in a studyset's new Files tab: uploaded from Add material (a file the studyset holds already asks first), each row with its pages, cards, notes and size, how far it is read and its reading deadline; renamed, given a deadline (a page or a chapter by a day), marked as read, started afresh, deleted with a moment to undo. The reader (/pdfs/:id) opens where reading left off: on wide windows a rail of tools (search, fit, zoom, fullscreen), a page counter with the chapter, and a sidebar; on phones a top bar, a page scrubber and a sheet. The sidebar holds the PDF's flashcards, by page or chapter, made from selected text or written there, each tied to its page and tagged with its chapter; and the page's note, an ordinary note tied to the page. Screenshots of a region become images that know their page. Cards and screenshots lead back to their page; reading on past a chapter with cards suggests studying it. Home shows the deadlines running and to come, and a timeline of them. Server: pdf_source rows (content in the payload, last writer wins) and an append-only pdf_reading log, the furthest page derived from it so devices never conflict. Files up to 50 MB for PDFs (20 MB for others; a larger file that isn't a PDF is deleted once stored). A deleted PDF takes its file's asset row along unless another PDF has the same file. Card payload 4 and note payload 2 keep the page. The reader draws with pdfrx (PDFium) behind PdfEngine in Dependencies; widget tests use a fake, and integration_test/pdf_engine_test.dart checks the real engine on a device or the desktop.
