Lower the bulk-digitization cliff with two more routes on top of the already-landed CSV import and "save and add another": - Photo-first drafts (capture now, catalogue later): burst-capture photos (camera or multi-gallery) into unnamed draft varieties, shown in a "to catalogue" tray, hidden from the main list until named. Adds Variety.isDraft (schema), addDraftVariety/watchDrafts/nameDraft, the triage sheet and the inventory banner. - On-device OCR label suggestion (Tesseract, offline, no Google): a "Suggest name from photo" button in the naming dialog behind a LabelTextExtractor interface (Tesseract on Android/iOS, no-op elsewhere). Reads the largest print via hOCR bounding boxes, drops boilerplate/low-confidence noise, preprocesses (grayscale, contrast, upscale) and sweeps rotations (0-315 deg) so tilted packets still read. Bundles tessdata_fast eng+spa; validated on-device against real packets. The photo is written to a temp file deleted immediately in a finally block (the plugin needs a path) - a bounded, documented exception to no-plaintext-at-rest. This commit also carries the co-developed schema evolution v5 to v8 that shares these files (organic flag, species viability years, crop calendar, lot provenance/abundance/preservation format, condition checks) plus their exports/migrations and i18n. Tests: CSV/draft/OCR unit + widget + migration green in isolation. Note: the full widget suite currently hangs (>10 min) - under investigation.
