UI improvements and Directory Picker Fix

[shey-cline]

• Option to open a card in detailed view when creating a task (if we want this)
• Replace trash icon on project cards on project rows with 3-dots dropdown menus
• Fully collapsible project sidebar (drag to collapse, shows project initials when collapsed)
• Fix directory picker cancel on macOS incorrectly showing manual path prompt
• Add indicator for drag and drop files

i will do the followup work on this to get it merged

[saoudrizwan]

Follow-up changes are pushed.

What changed:

• Made the last-used start action sticky in the new task dialog, so the primary button flips between "Start task" and "Start and open" and the dropdown always shows the other action
• Kept the new shortcut visible in the More shortcuts list
• Updated the related board-card test

Validation:

• npm --prefix web-ui run typecheck
• npm --prefix web-ui run test
• pre-commit repo checks also passed during commit

Note: I did not re-add the directory picker change here since that fix is already on main; this branch should just be rebased or updated against main to drop that diff noise.

Rebased this branch onto main and resolved the merge conflict in web-ui/src/components/project-navigation-panel.tsx.

What I kept during conflict resolution:

• the project actions three-dots menu
• the sidebar collapse/resize behavior
• the shortcut update for Start and open

Validation after rebase:

• npm --prefix web-ui run typecheck
• npm --prefix web-ui run test
• 56 test files passed
• 284 tests passed
