Team screen restyle + shared Button control

[nghtctrl]

Changes:

• New control/Button.tsx: MUI Button that wraps its label in <Typography noWrap variant="button"> so text ellipsizes instead of wrapping; disableTypography opts out for icon-only content. Exported from control/index.ts
• New Team/TeamPanel.tsx: bordered icon/title/actions header over a Grid container spaced on theme.layout.gap. TeamItem and PersonalItem now use it; the old TeamPaper / TeamHeadDiv / TeamName controls are deleted
• New Team/CardSize.tsx + useCardSize.ts: cards report the height their content needs and read back the maximum, so project/add cards across all team panels share the tallest card's height (floor 176px). Heights live in a ref so a card re-measuring only re-renders when the max moves
• theme.ts button styling rebuilt around a named colors map with explicit hover/active/disabled per variant+color; outlined is now the default variant, contained primary dark / contained secondary light, plus size-based heights (28/36/44). Removed the IconButton variant augmentation and the containedBg / containedHoverBg / BUTTON_SHADOW exports that existed only to mimic it. Secondary #00A7E1 (this was actually just primary.light color) → #90a828 (green olive color extracted from APM logo); added palette.custom.black
• ProjectCard and AddCard rebuilt as Grid items with a CardActionArea and the shared height; ProjectMenu absolutely positioned in the card corner, ProjectDialog lifted out of the clickable area. Icons: BsPencilSquare → EditSquareIcon, hand-drawn "B" → FormatBoldIcon
• TeamScreen and TeamProjects Grid layouts replaced with flex Box (sidebar + vertical Divider + scrollable content); AltButton → Button in TeamActions, TeamItem, PersonalItem
• New subscribePendingMediaUploads dispatches a window event on save (localStorage storage events only reach other windows); TeamActions consumes it via useSyncExternalStore so the badge count is live instead of refreshing only on dialog open/close. Test added
• Hard-coded margins/paddings replaced with theme.layout.gap
