Summary

This PR adds support for maximum community trust level and maximum community score limits for CDK projects, so creators can target newer users more easily.

Changes

• Added trust_level_limit_type and score_limit_type to project data and API payloads
• Extended backend requirement checks to support both minimum and maximum trust/score limits
• Updated project list filtering logic to match the new eligibility rules
• Redesigned the create/edit project dialog to use explicit 最低 / 最高 limit modes
• Updated project cards and receive page metadata to display the new limit direction clearly
• Improved receive button messaging for cases like 信任等级过高 and 社区分数过高
• Kept old projects backward-compatible by defaulting new limit types to minimum behavior

Notes

• Project creators can still view their own project detail page even if they do not satisfy the configured maximum limit
• Swagger docs were not regenerated in this change because swag was not available locally
• Frontend production build may still depend on external font access (fonts.gstatic.com) in restricted network environments
