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

When zones have Units='Percent' in the database but their Coords contain
pixel values (>100), ParsePercentagePolygon treats them as percentages,
causing wild scaling (e.g., 639% * 1920 / 100 = 12269) followed by
clamping to monitor bounds, producing degenerate full-frame zones.
Add a pre-check in Zone::Load that scans coordinate values before calling
ParsePercentagePolygon. If any value exceeds 100, log a warning and use
ParsePolygonString (pixel path) instead. Also add unit tests for both
ParsePolygonString and ParsePercentagePolygon.

Move the ISO 8601 time formatting function to zm_time.cpp/h so it is
reusable and not duplicated. Remove the local copies from
zm_monitor_onvif.cpp (was static) and tests/zm_onvif_renewal.cpp
(was a copy for testing). Both now use the shared declaration from
zm_time.h.

Cameras like Reolink send alarm=true but never send the corresponding
false, causing alarms to stick indefinitely. Use the TerminationTime
from PullMessagesResponse to auto-expire stale per-topic alarms.
- Add AlarmEntry struct with value and termination_time fields
- Extract TerminationTime from each PullMessagesResponse and attach
it to alarm entries; refresh on re-trigger so active alarms persist
- Sweep expired alarms after processing messages and on poll timeout
- Add expire_alarms option (default: true) to disable via onvif_options
- Fix TOCTOU race: remove unsynchronized alarms.empty() check before
acquiring mutex in the timeout sweep path
- Simplify SetNoteSet with C++17 structured bindings
- Add Catch2 tests for alarm expiry logic (mirrored struct to avoid
gSOAP header dependency)

Add cleanup_subscription() helper method that properly unsubscribes
from ONVIF cameras with error handling. This prevents subscription
leaks when renewals fail or when restarting subscriptions.
Changes:
- Add cleanup_subscription() method to header and implementation
- Call cleanup on renewal failures in Renew()
- Call cleanup when start() detects existing soap context
- Improve destructor logging for unsubscribe failures
- Add test documentation for cleanup behavior

- Add subscription_termination_time and next_renewal_time tracking to ONVIF class
- Add update_renewal_times() helper method to parse and store termination times
- Initialize renewal tracking in constructor
- Capture TerminationTime from CreatePullPointSubscriptionResponse
- Update times after successful Renew operations
- Implement conditional renewal logic in WaitForMessage() to only renew 10 seconds before expiration
- Add unit tests for renewal timing logic
This reduces unnecessary ONVIF traffic by only renewing subscriptions when needed,
following ONVIF specification best practices.

Using the Sutherland-Hodgman algorithms convex and concave subject polygons can be clipped
by convex clip polygons.
For now we only need clipping to rectangles (Box), so limit our implementation to that. If needed this can be
trivially extended to convex clip polygons (a check whether the clip polygon is actually convex has to be added).
If convex clip polygons are needed we have to switch to e.g the Vatti algorithm.
The size/variant specific character padding should be stored with the font data.
Modify the FontBitmapHeader accordingly and introduce a version field in the FontFileHeader
so we are able to check we have a font file with the right structure associated with that version.
The version field is set to 1 in this changeset.
Those tests timeout on Cirrus. Disable them for now.
This introduces a new tag [notCI] with which tests can be marked which shouldn't be run during CI.
