Dismisses some gosec rules in test code where they do not apply, since
they show up when running `golangci-lint run` locally and make it harder
to spot newly introduced errors.

## Testing
- [x] Added/updated automated tests
- [ ] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [ ] QA'd all new/changed functionality manually

**Related issue:** Resolves#36494
Fixes:
- Allow matching software to title solely by non-empty upgrade code
- Match names case-insentive and trimmed whitespace and special unicode
characters (in our osquery-perf dataset)
- Match bundle ID case-insensitive

## Summary by CodeRabbit
* **Bug Fixes**
* Different variations/versions of the same software that share the same
upgrade code are now unified under a single software title, preventing
duplicate titles and improving linkage across releases.
* **Tests**
* Added a test verifying that entries with the same upgrade code but
different names link to an existing shared title.

* Improved software title matching to be case-insensitive, preventing
duplicate entries for the same software reported with different
capitalization.
* Enhanced upgrade code reconciliation logic to properly detect and
handle conflicts when multiple software entries share upgrade codes.
* **Tests**
* Added test coverage for case-insensitive software title matching and
upgrade code reconciliation scenarios.

This PR addresses Issue 3 in the above unreleased bug: when a new
`software` comes in, its `upgrade_code` is compared with that of any
corresponding `software_title`s, and reconciled appropriately - see code
for the various cases
## Testing
- [x] Added/updated automated tests
- [x] QA'd all new/changed functionality manually
- [x] Load tests: @AndreyKizimenko since I don't think you've load
tested the original story yet, this change will be covered by those
tests when you do

## Summary by CodeRabbit
* **Bug Fixes**
* Ensured upgrade_code values on existing software titles are
consistently updated when incoming data provides non-empty values; added
logging and safe retry handling for anomalous states.
* **Tests**
* Added table-driven tests covering upgrade_code reconciliation
scenarios (empty, non-empty, conflicting, NULL) and verification of
resulting title values.
* **Refactor**
* Introduced a lightweight software title summary type and updated
internal mappings to streamline pre-insert and reconciliation
processing.
