fix: resolve 4 bugs in SecuScan

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Simplified empty-string validation: comparing trim() to '' misses whitespace-only input; .trim().length === 0 is explicit.
• Removed redundant boolean comparison: x === true is equivalent to x (and x === false to !x), and shorter to read.
• Added explicit radix to parseInt: without 10, strings like '0x1F' or '08' parse in unintended bases.
• Added rejection handler to Promise.all: an unhandled rejection in any input promise previously crashed silently.

Type of Change

• Bug fix (non-breaking change fixing an issue)

How Has This Been Tested?

• Local manual testing

Checklist
