v0.4.0: 再平衡建议、清晰提示、可靠汇总 / Rebalance Guidance, Clear Tooltips, Reliable Totals

本次更新让再平衡建议更可执行，并修复录入提示和迁移后总览数据的显示问题。

🎉 新功能

• 再平衡提醒现在会显示当前金额、目标金额，以及建议增持或减持的金额，方便直接判断下一步操作。
• 目标占比为 0% 或未设置的资产不会影响其他资产的建议；当某位成员的目标占比合计不是 100% 时，界面会明确提示差额并暂停给出调仓金额，避免误导。
• 总览页和分析看板都会展示新的金额建议；“一键归一化”只调整已设置正目标占比的资产。

🐛 Bug 修复

• 修复新增资产或负债时，分类、金额和期望占比说明在弹窗边缘被截断的问题；提示现在会自动调整方向并保持完整可见。
• 修复导入迁移包后，资产明细已经恢复，但总览净资产、总资产、总负债和趋势仍显示为零的问题。

This update makes rebalance guidance directly actionable and fixes clipped entry guidance and incorrect Overview totals after migration imports.

🎉 New features

• Rebalance alerts now show current amounts, target amounts, and suggested buy or sell amounts so the next action is clear.
• Assets with a 0% or unset target no longer distort guidance for other assets. If a member's targets do not total 100%, the app shows the gap and pauses adjustment amounts instead of presenting misleading advice.
• The new amount guidance appears on both Overview and Analytics, while one-click normalization only adjusts assets with positive targets.

🐛 Bug fixes

• Fixed category, amount, and target-ratio guidance being clipped near the edges of the asset and liability entry dialog. Tooltips now reposition automatically and remain fully visible.
• Fixed Overview net assets, total assets, total liabilities, and trend values remaining at zero after a migration import restored the holdings.
