Improve error recording for macro cache generation#354

Pull request overview
This PR aims to improve developer-visible error recording during server-side macro cache generation by capturing FreeCAD console output (via Python logging) and persisting per-macro error details, alongside additional validation/error reporting for problematic icons.
Changes:
- Record FreeCAD console warnings/errors emitted during macro parsing into
macro_errors.jsonas per-macro lists (via a bounded in-memory logging handler). - Add/adjust macro metadata warnings (e.g., defaulting missing licenses) and normalize warning/message formatting.
- Add PNG inspection to detect duplicate embedded ICC profile chunks and surface warnings/errors for addon/macro icons.

| File | Description |
|---|---|
| addonmanager_macro_parser.py | Adds warning/default behavior when a macro omits a license string; tweaks warning/message formatting. |
| addonmanager_icon_utilities.py | Introduces PNG chunk inspection helpers and a new icon creation debug print. |
| MacroCacheCreator.py | Captures console/log output per macro via a deque-backed logging handler; records multiple errors per macro; adds PNG iCCP-related warnings. |
| AddonCatalogCacheCreator.py | Records an icon error when PNG data contains duplicate ICC profile chunks. |

The new PNG validation path (.png + png_has_duplicate_iccp) isn’t covered by the existing CacheWriter.generate_cache_entry_from_package_xml tests (which currently only exercise SVG icons). Adding a unit test that feeds a PNG with duplicate iCCP and asserts an entry in icon_errors (and expected icon_data behavior) would help prevent regressions.

Type annotation chunk_types: list[bytes] is not compatible with Python 3.8 (built-in generics aren’t subscriptable without postponed evaluation), which this repo still supports/tests. Use typing.List[bytes]/typing.Sequence[bytes] (or quote the annotation / enable from __future__ import annotations) to avoid runtime import errors in 3.8.

This error message string includes a trailing newline (\n), which will end up embedded in macro_errors.json and can complicate downstream display/processing. Consider removing the newline and letting the consumer control formatting.

Catch the console error output from the macro class while it builds the macros, and record it to a developer-visible log location on addons.freecad.org.
