fix(rclonecli): improve vfs cache refresh/forget logic and parameter types

[drondeseries]

Problem

The rclone VFS cache refresh/forget calls had two issues:

1. Wrong parameter types — some rc call parameters were passed as string where the rclone RC API expects other types, causing silent failures or ignored cache refreshes
2. Incorrect refresh vs forget logic — the code was calling vfs/refresh in cases where vfs/forget is the correct operation (and vice versa), meaning newly imported files were sometimes not appearing in the mount, or stale entries were not being evicted

Fix

• Corrected parameter types for vfs/refresh and vfs/forget RC calls
• Clarified when to use refresh (populate new dir entries) vs forget (evict stale cache) based on the operation context
• Improved error handling and logging for VFS RC calls

Impact

Newly imported files now reliably appear under the rclone mount without requiring manual cache refreshes or container restarts.
