Use Random.hex for base component unique ID

[aduth]

🛠 Summary of changes

Updates BaseComponent to use Random.hex instead of SecureRandom.hex.

These IDs are not security-sensitive, and merely need to be reasonably unique within instances of the component of a single request, to satisfy HTML validation of unique IDs across elements (ref).

Benchmark:

require 'benchmark/ips'
require 'securerandom'

Benchmark.ips do |x|
  x.report('SecureRandom.hex') do
    SecureRandom.hex(4)
  end

  x.report('Random.hex') do
    Random.hex(4)
  end

  x.compare!
end
