…n uv export

Skip PEP 440 direct references (name @ url) and path dependencies (./,
../, /) in parseUvExport() with a log.fine() warning instead of throwing
an IOException. These lines lack pinned versions needed for the dependency
graph. Set currentKey to null after skipping to prevent # via comments
from corrupting the graph of other packages.

Implements TC-4538

## Summary
- Adds `preprocessRequirementsLines()` to `PythonControllerBase` that
properly handles all requirements.txt line types before dependency
resolution
- Fixes parsing errors when requirements.txt contains
`--extra-index-url`, `--hash`, line continuations (`\`), and other
non-package lines
- Handles: pip options, inline options (--hash, --config-settings), line
continuations, PEP 508 direct references (`name @ url`), bare URLs, VCS
URLs, and local paths

Fixes [TC-4527](https://redhat.atlassian.net/browse/TC-4527)

## Test plan
- [x] 13 unit tests covering all requirements.txt line types
- [x] Existing `getIgnoredDependencies_strips_environment_markers` test
passes
- [ ] Manual verification with requirements.txt files containing
`--extra-index-url` and line continuations

## Summary by Sourcery

Improve Python requirements.txt preprocessing to robustly handle pip
options, hashes, line continuations, and non-package lines before
dependency resolution.

Bug Fixes:
- Fix handling of requirements.txt entries that include pip options,
hashes, line continuations, direct references, bare URLs, VCS URLs, and
local paths so they no longer break dependency parsing and installation.

Enhancements:
- Introduce a reusable preprocessing routine for requirements.txt lines
and apply it across Python dependency resolution and ignored-dependency
detection to ensure consistent parsing behavior.

Tests:
- Add unit tests covering preprocessing of all supported
requirements.txt line variants, including pip options, hashes, line
continuations, direct references, URLs, local paths, and mixed
scenarios.
