Restore to commit 11a233f + add text message saving for ZGR group with detailed HELP_INSTRUCTIONS

Fix: separate filename timestamp (20260819_080847) from record timestamp (2026-08-19 08:08:47) to prevent ArrowInvalid when dataset viewer parses timestamp field. Also fix proxy template to use same pattern.

Fix: extract photo_url from logs, debug info shows actual image URL, check save results, add time field, use photo field from Zalo API + OCR with Vintern-1B for Vietnamese text extraction

Fix: use photo field from Zalo API, add Vietnamese OCR with Vintern-1B, include photo_url in logs, check save result before logging success, add time field to all log entries, OCR text parsing for product_name/description/price/category

Fix: include photo_url in logs, check save result before logging success, add time field to image event logs, save caption as description

Fix: handle message.image.received events with photo_url from Zalo - save images to main dataset (zgr-b7e1e71cf5701c2e4561)

Fix SyntaxError: bracket escaping in f-strings for ZGR logs page

Emergency fix: ZGR logs page now displays ALL webhook events including sender_id, text, image_url, and metadata. Previous version had no logs because sender_id filter was too strict.

Fix proxy-spaces page rendering - use f-string properly with pre-computed values

Fix SyntaxError: replace nested f-string with string concatenation to avoid escape character issues. Use f-string with weight variable instead of inline expression with quotes.

Restore full app.py with all fixes: CSS brace fix, MAIN_DATASET_ID, zgr logs tab, success message with zalo.me link

Restore full app.py with all fixes (CSS brace fix, main dataset, zgr logs tab, success message)

test

Add: zgr-b7e1e71cf5701c2e4561 logs tab + dual dataset save + product name extraction + success message with zalo.me link + CSS brace fix

Fix: escape CSS braces in proxy template + add MAIN_DATASET_ID for centralized product data collection from all users

Update: include zalo.me bot link in success notification so users can continue setup on their own bot

Fix: escape CSS braces in proxy template f-string to prevent NameError(font) when creating proxy spaces

Add dataset auto-creation, /proxy-spaces management page, clean template

Fix: proper HTML string concatenation in proxy-spaces route

Fix: always send detailed success reply; add /proxy-spaces page on proxy space

Add dataset auto-creation per user with image/desc/price/category, delete button, and improved webhook reply

Add delete button on /proxy-spaces and unique proxy space names

fix: handle rate limit (429) for Space creation + pre-check if Space already exists before create_repo

fix: use content variable instead of inline ternary in proxy template to avoid nested quotes syntax error

fix: escape log variable in proxy template f-string ({{log['event']}} not {log['event']}) — prevents KeyError during template evaluation; fixes 'name log is not defined' error when creating proxy spaces

fix: use path_or_fileobj param name for upload_file (huggingface_hub 1.27 API fix)

feat: persist proxy spaces to Space repo file (proxy_spaces.json) so list survives rebuilds; add _load_proxy_spaces on startup + _save_proxy_spaces after creation

fix: proxy space /logs endpoint — use PROXY_NAME instead of undefined repo_id variable

fix: correct audioop stub syntax; add GET /webhooks to proxy, /logs page in proxy, auto-reply welcome msg, auto setWebhook with user token, /proxy-spaces management page + Gradio tab

fix: Dockerfile ENV backslash escaping causing BUILD_ERROR in proxy spaces

fix: add create_repo before upload_folder (proxy space must exist first); handle HF_TOKEN env discovery in Spaces

fix: auto-discover HF_TOKEN via get_token() fallback + clear error when missing; ensure Space can create proxy sub-spaces

fix: add missing 'import requests' in proxy space template; use pathlib.Path for tmp file creation

fix: use pathlib.Path(tmp, ...) instead of f-string {{tmp}} which produced literal '{tmp}' path

feat: help instructions use proxy URL pattern + logs page redesign for detailed user info

fix: correct bot naming examples in help instructions

fix: parse Zalo webhook payload under result.* + log detail (name/id/chat_type) + reply all messages with bot creator setup guide
