Moved the defaulting of the 'resume' parameter to later in the initialization process to ensure correct precedence. Added unit tests to verify that the resume parameter can be set via environment variable and that explicit arguments override environment variables.

* Add support for 'online' mode as alias for 'cloud'

Updated the documentation to clarify that 'online' is an alias for 'cloud' mode and removed 'online' from the MODES Literal. Added a test to ensure that initializing with mode='online' results in 'cloud' mode being set.

* Handle backup write errors and improve timer cancel

Added error handling for backup file write failures in porter/__init__.py to prevent crashes when backup mode is not enabled. Updated MonitorCron.cancel in run/helper.py to join the timer thread after cancellation for better thread management.

* Fix monitor condition and update test epochs

Corrected the logic for enabling system monitoring in SwanLabRun by changing the condition from 'or' to 'and'. Increased the number of epochs in the test_sync unit test to 10000 for more extensive testing.

Updated the logic for assigning section names and types based on key and section_type. Now, PUBLIC and CUSTOM types use the prefix before a slash in the key as the section name, and CUSTOM type is treated as PUBLIC. SYSTEM, PINNED, and HIDDEN types do not assign a section name.

* Fix error key usage in SwanLabKey class

Corrected the keys used to extract 'expected' and 'got' values from the error dictionary to 'excepted' and 'data_class', ensuring proper error handling in the SwanLabKey class.

* Update error field names in key handling and tests

Changed error dictionary keys from 'expected' and 'got' to 'excepted' and 'data_class' in both SwanLabKey and related unit tests for consistency. Updated error message assertions to reflect new field names.
