joshsiv-mulga 9ed59aac79 fix(e2e): prevent silent set -e abort on var=$(func) patterns 
When a function returning non-zero is captured via command substitution
under `set -euo pipefail`, the assignment exits the script before the
following `if [ -z "$var" ]` diagnostic can run. CI failures showed up
as a sudden jump to the EXIT trap with no error message.

- run-multinode-e2e.sh: wrap get_remote_ssh_port in `if !`, bump retry
  10 -> 30, add dump_guest_ssh_diagnostics on miss
- run-pseudo-multinode-e2e.sh, run-e2e.sh: wrap get_ssh_port in `if !`
- run-lb-e2e.sh: add `|| VAR=""` fallback on pick_peer

# Consolidated LB Data Plane E2E Test
# Tests all 4 LB variants: ALB internet-facing, ALB internal, NLB internet-facing, NLB internal.
# Shares a single VPC, subnet, and set of dual-purpose app instances across all suites.
# ALB + NLB run in parallel within each phase (internet-facing / internal).
#
# Requires: Pool mode with external IPAM (NOT dev_networking).
#
# Usage:
# ./tests/e2e/run-lb-e2e.sh # internal-only (single-node)
# ./tests/e2e/run-lb-e2e.sh --peer <ip> # all 4 variants (multi-node, legacy)
# ./tests/e2e/run-lb-e2e.sh --nodes <ip1> <ip2> ... # all 4 variants (multi-node, preferred)
