Add a new AUDIT logging level (-5) between PANIC (-4) and NOLOG (shifted
to -6) across C++, PHP, and Perl loggers. AUDIT entries use code 'AUD'
and syslog priority LOG_NOTICE. They record who changed what, from where,
for monitors, filters, users, config, roles, groups, zones, states,
servers, storage, events, snapshots, control caps, and login/logout.
AUDIT entries have their own retention period (ZM_LOG_AUDIT_DATABASE_LIMIT,
default 1 year) separate from regular log pruning. The log pruning in
zmstats.pl and zmaudit.pl now excludes AUDIT rows from regular pruning
and prunes them independently.
Critical safety: the C++ termination logic is changed from
'if (level <= FATAL)' to 'if (level == FATAL || level == PANIC)' to
prevent AUDIT-level log calls from killing the process.
Includes db migration zm_update-1.39.1.sql to shift any stored NOLOG
config values from -5 to -6.

Convert zone coordinates from absolute pixel values to percentages
(0.00-100.00) so zones automatically adapt when monitor resolution
changes. This eliminates the need to manually reconfigure zones after
resolution adjustments.
Changes:
- Add DB migration (zm_update-1.37.81.sql) to convert existing pixel
coords to percentages, recalculate area, and update Units default
- Add Zone::ParsePercentagePolygon() in C++ to parse percentage coords
and convert to pixels at runtime using monitor dimensions
- Backwards compat: C++ Zone::Load() checks Units column and uses old
pixel parser for legacy 'Pixels' zones
- Update PHP coordsToPoints/mapCoords/getPolyArea for float coords,
replace scanline area algorithm with shoelace formula
- Update JS zone editor to work in percentage coordinate space with
SVG viewBox "0 0 100 100" and non-scaling-stroke for consistent
line thickness
- Position zone SVG overlay inside imageFeed container via JS to align
with image only (not status bar)
- Support array of zone IDs in Monitor::getStreamHTML zones option
- Update monitor resize handler: percentage coords don't need rescaling,
only threshold pixel counts are adjusted
- Add 8 Catch2 unit tests for ParsePercentagePolygon
