Add missing descriptions to 17 artifacts

[abrignoni]

What

Fills in empty or absent `description` fields in the `artifacts_v2` metadata block for 17 iOS artifacts. The `description` renders in the artifact's HTML report header and is carried into LAVA, so these previously showed no explanation of what the artifact does.

Each description was written from the artifact's actual paths, SQL query and output columns (not guessed), following the existing house style ("Parses X from Y").

Notes

• No parser logic changed — metadata only.
• One extra line: a `# pylint: disable=broad-exception-caught` pragma on `fmfdDevices`' existing per-file resilience `except` (log-and-continue), so the now-touched file lints at 10.00/10. No behavior change.
• Verified: all 17 `artifacts_v2` blocks parse with a non-empty description; PluginLoader loads 598 plugins; `pylint --disable=C,R` on all changed files exits 0 at 10.00/10; CRLF files kept CRLF.
