feat(openclaw): add Workspace Files panel for managing bootstrap md files

Add a dedicated panel to read/write OpenClaw's 6 workspace bootstrap files
(AGENTS.md, SOUL.md, USER.md, IDENTITY.md, TOOLS.md, MEMORY.md) directly
from ~/.openclaw/workspace/, with a whitelist-secured backend and Markdown
editor UI. Also fix prompt auto-import missing OpenCode/OpenClaw and the
PromptFormPanel filenameMap type exclusion.
