feat(hogli): support 200 GiB devboxes

[rnegron]

Problem

• hogli devbox:start --disk only offered 60 / 80 / 100 GiB. The posthog-linux Coder template has since moved on: 100 GiB is the golden-AMI floor (smaller volumes fail at launch with InvalidBlockDeviceMapping), and it now exposes a 200 GiB option. So the CLI advertised two sizes that fail at launch and couldn't create the larger boxes the template supports.

Changes

• --disk choices are now 100 / 200, matching the template's disk_size options.
• Added a comment tying the choice list back to the template so the two stay in sync.

How did you test this code?

• Added test_devbox_start_forwards_larger_disk_size: asserts --disk 200 is accepted and reaches create_workspace as disk_size="200". No existing test covered a non-default disk, so this guards the choice list drifting from the template's valid options.
• ruff check / ruff format clean, hogli ci:preflight --strict passes.

Docs update

• None. The infra-side disk options live in posthog-cloud-infra, not this repo.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

• Authored by Claude (Opus 4.8) at Raúl's direction. Skill invoked: /writing-tests.
• Source of truth for valid sizes is the posthog-linux template's disk_size parameter (100/200 GiB). I dropped the below-floor 60/80 options rather than only adding 200, since those now fail at launch.
