refactor(scripts): extend shared JS modules for status maps and filters

status_maps.js:
- Add taskStatusMapAbbrev for compact output (dump_database)
- Add projectStatusMapAbbrev for compact output

filters.js:
- Add isWithinDays(date, days, requirePastOrPresent) helper
- Refactor date range checks to use new helper
