Fix UnboundLocalError in memory injection when facts are empty (#3992 )

`format_memory_for_injection` bound `facts_header` / `all_fact_lines` only
inside the `if isinstance(facts_data, list) and facts_data:` block, but the
structure-aware overflow-truncation path at the end of the function
references both unconditionally.

When a user's memory has sizeable user-context / history (so `sections` is
non-empty and the assembled output exceeds `max_tokens`) but an empty or
missing `facts` list, that block is skipped, so the truncation branch hits
`UnboundLocalError: cannot access local variable 'all_fact_lines'` and
aborts memory injection entirely.

Hoist the two initializers to function scope, alongside the existing
`guaranteed_line_tokens = 0`, so they are always bound. Behaviour is
unchanged when facts are present.

Adds a regression test (empty facts + oversized user context) that fails
with UnboundLocalError before the fix and truncates gracefully after.
