fix(electrobun): wizard creation flow + GitLab probe + shell detection + dropdown flip

- Git probe tries GitHub then GitLab for owner/repo shorthand
- Shows "Found on GitHub/GitLab" with platform indicator
- system.shells RPC detects installed shells (bash/zsh/fish/sh/dash)
- CustomDropdown flip logic uses 200px threshold for flip-up
- Project creation properly persists all wizard fields + adds card
