utcnow_iso() now produces 'YYYY-MM-DD HH:MM:SS' (space separator) matching
SQLite's datetime('now') so lexicographic comparisons like
'published_at <= datetime(now)' work correctly.
Also add `id DESC` tiebreaker to get_ledger() ORDER BY to preserve
insertion order when multiple credits are added within the same second.

Migrates 15 source files from the deprecated datetime.utcnow() API.
Uses utcnow() for in-memory math and utcnow_iso() (strftime format)
for SQLite TEXT column writes to preserve lexicographic sort order.
Also fixes datetime.utcfromtimestamp() in seo/_bing.py.

git mv all tracked files from the nested padelnomics/ workspace
directory to the git repo root. Merged .gitignore files.
No code changes — pure path rename.
