[GRDM-57838] Log user file/folder-zip downloads in Recent Activity; suppress internal system downloads

[ndnhat1]

Purpose

Implements the download history display feature (ダウンロード履歴表示機能).

Currently, file download and folder ZIP download actions are silently discarded — create_waterbutler_log() returns early for these action types without creating any log entry. As a result, "Recent Activity" never shows download events.

This change:

• Enables logging of user-initiated file downloads and folder ZIP downloads in "Recent Activity"
• Suppresses logging for internal system operations (ONLYOFFICE editor load, timestamp verification, metadata sync, export/restore, etc.) that also trigger WaterButler download callbacks but should not appear as user activity

Changes

Core logging — addons/base/views.py

• Remove the early-return that discarded all download actions in create_waterbutler_log(); add NodeLog creation for download_file and download_zip
• Add MFR render detection in get_auth() to suppress file preview/inline editor loads from appearing as user downloads

Internal request suppression — api/base/utils.py

• URL builder auto-appends callback_log=false to all internal WaterButler requests (excluding meta= and requests with an explicit callback_log), structurally suppressing system-initiated operations without requiring per-caller changes

Frontend display messages

• Add *_file_downloaded and *_folder_downloaded_zip entries to all addon LogActionList JSON files
• Update logActionsList.json, anonymousLogActionsList.json, logActionsList_extract.js, and translation files
• Add *_file_downloaded actions to acceptableLinkedItems in logTextParser.js

Tests

• Update related unit test cases
