Upgrade ses to 1.14.0 to fix iterator helpers incompatibility

[Copilot]

UI fails to load with TypeError: Accessor not expected at intrinsics.%IteratorPrototype%.constructor due to ses incompatibility with JavaScript iterator helpers.

Changes

• Bump ses from 1.8.0 to 1.14.0 in root package.json resolutions
• Bump ses from ^1.8.0 to ^1.14.0 in ui/package.json devDependencies
• Update yarn.lock with new ses dependencies (@endo/cache-map, @endo/[email protected], @endo/immutable-arraybuffer)

Version 1.14.0 includes fixes for iterator helper compatibility that resolve the lockdown initialization error.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• download.cypress.io
  • Triggering command: /usr/local/bin/node index.js --exec install (dns block)
• edgedl.me.gvt1.com
  • Triggering command: /usr/local/bin/node install.mjs (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>UI error probably link to a use of a deprecated version of ses</issue_title>
<issue_description>Going through the video tutorial associated to the dapp, I manage to go through up until the launching of the dapp with yarn start:ui. The dapp is launched and open on localhost on port 5473 but the the browser displays a blank page and I get the following errors in the console:

• Do you have ideas where this could come from?

I personally looked at the ses (hardened javascript) dependency and it seems that we are using a deprecated version (0.18.8) according to the npm package webpage: "Please upgrade to ses@^1.1.0. Version 0.18.8 breaks in the presence of the new JavaScript iterator helpers."
I believe the issue might come from there. 

I then had a bit of struggle to completely remove the use of deprecated ses instance in dependencies and sub dependencies of the project. I tried to use resolutions but I am not sure this is working perfectly.  

• Do you think this deprecated ses version could be the issue? If so, how to completely get rid of deprecated subdependencies use?</issue_description>

e2e tests are failing in ci; it's not obvious to me why

investigating is well below other priorities for me just now
