Chore: silence debug logging across all pages (log_lvl → 0)

Set log_lvl to 0 in all pages and layouts that had it left at 1 or 2
from development. Also remove two hardcoded `log_lvl = 2` overrides
inside function bodies in reports_files.svelte and
reports_presenters.svelte that were forcing verbose output regardless
of the module-level setting.

Affected: launcher location page, leads pages (2), pres_mgmt reports (2),
presenter +page.ts, IDAA layouts (2), IDAA archives, IDAA recovery
meetings page, journals pages (2).
