🤖 This is an automated pull request to update docmost to version v0.25.1. This PR must be reviewed and tested before merging.

Auto-generated update considerations:

• API pagination changed from offset-based to cursor-based pagination. If using the API directly with pagination, code changes are required.
• Search API endpoints now return data.items[] instead of data[] format.
• New environment variable available: HOST binding is now configurable for IPv6 support.
• Database driver migrated from node-postgres to postgres.js, which may affect connection behavior or performance characteristics.
• Logging system switched from previous logger to pino, which may change log format and output.
• Large file upload support added, may require reviewing any file size limits or storage configurations.
• Tiptap editor upgraded to V3, which is a major version change that could affect editor behavior.
