fix: downgrade and fork reown (#2566)

Due to reown changing their license in version
1.2.0 we switched to use last open source release
of reown with all fixes for flutter 3.32.0 and
16kb page size requirements.

chore: drop dependency overrides for reown
ci: switch prebuilds to use github releases instead of CDN
fix: reown socket errors in onDone and onError
fix: remove flutter_secure_storage on linux (closes #2577, #2561)
