Add securitypoolx2 simulation scenario and hide pool manager addresses

[KillariDev]

Summary

• Added a new securitypoolx2 simulation scenario that boots two seeded security pools with two vaults each.
• Extended simulation bootstrap, scenario labels, and documentation to recognize the new seeded scenario.
• Removed manager address display from security pool UI sections and updated tests to match the new behavior.
• Added simulation backend coverage for the new scenario and tightened existing security-pool assertions.

Testing

• Not run in this summary generation step.
• Updated and added tests covering scenario normalization/labels, security pool UI expectations, and securitypoolx2 bootstrap behavior.
• Repository guidelines indicate the change set should be validated with bun run tsc, bun run test, bun run format, bun run check, and bun run knip before merge.
