Fix FTP upload file handle leak, correct deploy warning typo, and add rsync config test

[zhang787jun]

Motivation

• Prevent leaking file descriptors during FTP deploy by ensuring uploaded files are closed after use.
• Correct a spelling mistake in the runtime warning to make messages clearer for users and maintainers.
• Add a unit test for get_rsync_configs to increase confidence in deploy configuration selection.

Description

• Updated deploy_ftp in fabfile.py to open files with a context manager (with open(..., 'rb') as upload_file:) before calling ftp.storbinary so each file is closed after upload.
• Fixed the unsupported deploy type message in fabfile.py to use not support {0} deploy method instead of the misspelled version.
• Added tests/test_fabfile.py which stubs optional dependencies (fabric and simiki) to allow importing fabfile, and includes a pytest test that patches fabfile.configs and asserts get_rsync_configs() returns the rsync entry.

Testing

• Ran pytest -q in the repository root and the test suite passed: 1 passed in 0.34s.
• Verified the modified deploy_ftp logic via static inspection and ensured the repository imports succeed in the test environment by stubbing optional modules.
