refactor(core): side bar resizing (#5280)

Rewrite sidebar panel using a customized react-resizable-panels version that supports sidebar pixel sizing (not using flex percentages). Now the left & right sidebar using the same `ResizePanel` impl. fix https://github.com/toeverything/AFFiNE/issues/5271 fix TOV-163 fix TOV-146 fix TOV-168 fix TOV-109 fix TOV-165
