ux: create parent directories before moving config files (#1127)

Fixes #1125 and #1114

The upload_config_file() function now creates parent directories
before moving config files to paths like ~/.claude/settings.json
and ~/.openclaw/openclaw.json.

Previously, if these directories didn't exist, the mv command would
fail with "No such file or directory" errors. This affected all
agents using setup_claude_code_config() and setup_openclaw_config().

Changes:
- Extract directory path using dirname
- Create parent directories with mkdir -p
- Execute chmod and mv in same command chain
