Reduce function complexity (C901 violations)

[aquarion]

Several functions exceed the max-complexity threshold of 10, triggering C901 flake8 warnings.

Affected functions

File	Function	Complexity
atproto_posts.py	Loop 52	17
destiny2.py	authenticate	12
facebook_posts.py	some_action	16
gw2.py	run_import	12
instagram.py	If 31	12
mastodon_toots.py	Loop 48	15
steam.py	If 35	12
tumblr.py	Loop 106	12
wordpress.py	Loop 44	15
wow.py	Loop 342	12
utils.py	niceTimeDelta	13

Suggested approach

1. Extract helper functions to break up complex logic
2. Use early returns to reduce nesting
3. Consider using dispatch tables or strategy patterns where appropriate

Priority

Low - these work correctly, just harder to maintain
