Prevent duplicate downloads on export/download buttons - #1659

The 'Export VEX' and 'Export VDR' buttons had no guard against repeated clicks. Each click started a new blob download, so clicking while a download was already in progress triggered multiple simultaneous requests and duplicate file downloads. Each handler now sets an in-progress flag (guarded early-return), the corresponding button is disabled and shows a spinner while the export runs, and the flag is reset in a finally() block so the button re-enables whether the download succeeds or fails.

The 'Download BOM' (inventory / with-vulnerabilities) and 'Download component' (CSV) dropdowns on the project Components view had no guard against repeated clicks, so each click started a new download and clicking while one was in progress produced duplicate downloads. Each handler now sets an in-progress flag (guarded early-return), the corresponding dropdown is disabled and shows a spinner while the export runs, and the flag is reset in finally() so it re-enables whether the download succeeds or fails.

Description
Export/download buttons started a new download on every click with no
in-progress guard, so clicking (or double-clicking) while a download was
already running triggered multiple simultaneous requests and duplicate file
downloads. This affected the project Findings view (Export VEX, Export VDR)
and the project Components view (Download BOM — inventory / with-vulnerabilities,
and Download component — CSV).
Each handler now sets an in-progress flag with a guarded early return, disables
the corresponding button/dropdown and shows a spinner while the export runs, and
resets the flag in a
finally()block so the control re-enables whether thedownload succeeds or fails.
Addressed Issue
fixes #1658
Additional Details
The frontend project has no component unit-test harness, so this was verified
manually: with the Network tab open (throttled to Slow 3G to widen the window),
rapid/double clicks on each export control now send only one request and produce
a single download, and the control re-enables after completion or error. Verified
on the Findings (VEX/VDR) and Components (BOM/CSV) views.
