Fix Python scripts failing to read relative paths in subdirectories + upgrade multer to patch DoS vulns

[Copilot]

Python scripts in subdirectories (e.g. btdr/app.py) had their working directory set to $dir_scripts root instead of the script's own directory, breaking relative file access like open('./config.json').

Root cause

run_normal() in shell/otask.sh had an [[ ${file_param} != /* ]] guard that skipped the cd into the script's subdirectory for absolute paths. run_concurrent() and run_designated() had no such guard and worked correctly.

Changes

shell/otask.sh

• Removed [[ ${file_param} != /* ]] && from the run_normal() path-handling condition — CWD is now correctly set to the script's directory for both relative and absolute invocations, consistent with the other run modes.

# Before — absolute paths skipped the cd, CWD stayed at $dir_scripts
if [[ ${file_param} != /* ]] && [[ ! -z ${relative_path} ]] && [[ ${file_param} =~ "/" ]]; then

# After — all paths with a directory component cd into the script's directory
if [[ ! -z ${relative_path} ]] && [[ ${file_param} =~ "/" ]]; then

shell/preload/sitecustomize.py

• Use os.path.abspath(sys.argv[0]) instead of bare sys.argv[0] when computing the script's relative path from dir_scripts. When Python is invoked as python3 app.py from a subdirectory, sys.argv[0] is just app.py; abspath resolves it to the full path first so task_before.sh receives btdr/app.py rather than a bare filename.

package.json / pnpm-lock.yaml

• Upgraded multer 1.4.5-lts.1 → 2.1.1 and @types/multer ^1.4.7 → ^2.0.0 to address 7 DoS CVEs (uncontrolled recursion, resource exhaustion, memory leaks from unclosed streams, unhandled exceptions from malformed requests). The v2 API is backwards-compatible with all usage in this codebase.

<issue_title>创建容器python读取不到相对路径</issue_title>
<issue_description>### Qinglong version

2.20.2

Steps to reproduce

Traceback (most recent call last):
File "/ql/data/scripts/btdr/app.py", line 32, in
with open('config.yaml', 'r', encoding='utf-8') as f:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'config.yaml'

app.py和config.yaml在同一个文件夹目录下,
之前程序可以跑, 被攻击后删除重新建, 升级最新版本都一样, 执行python的路径正常, 但是python运行的时候它获取当前目录不是程序所在目录, 写出config.yaml的绝对路径是可以运行的, 因为很多脚本包括以后写的都使用程序所在目录读取文件,所以这个问题怎么解决 ,
