Refactor interactionR_table: Simplify and standardize table saving interface

[LeafLight]

background

The current implementation of interactionR_table has several usability and reproducibility issues regarding table export:

• The file_path parameter is ambiguous: it is unclear whether it expects a directory or a full file name, and it does not allow users to specify a custom file name directly. (And it use path <- paste(file_path, "interaction.docx", sep = "\\")).
• The function uses hard-coded file names and directory logic, making it difficult to control output location and file naming.
• There is an interactive prompt (askYesNo) for saving, which is not suitable for automation

Proposal

Replace the file_path parameter with a single file argument that accepts either a full file path (including file name) or a directory. If a directory is provided, use a sensible default file name (e.g., interaction_table.docx)
