fix(custom-model): address PR #430 pre-merge review (Ark0N)

Four blockers from the 2026-09-18 review:

- PUT /api/model-endpoints/:id now merges modelContextLengths/
  modelSizesGB back in from the stored record instead of trusting the
  editor's body, so renaming an endpoint or changing its default model
  no longer silently drops the context-window floor check and
  CLAUDE_CODE_MAX_CONTEXT_TOKENS injection.
- custom-model:swapped-out is now session-scoped (added to
  SESSION_PREFIXES) instead of broadcasting to every connected client.
- The quick-start custom-model path now hands setCustomModel() only
  the endpoint's own injected env vars, not the full merged set,
  matching the restart-in-place path — the full set put
  CLAUDE_CODE_EFFORT_LEVEL back after the Session constructor had
  already stripped it.
- The quick-start launchModel override for pi/grok/omp is now applied
  generically via the registry's legacyConfigField, mirroring
  Session._withCustomModelLaunchModel, instead of three hardcoded
  mode === '<id>' branches a future CLI's injection recipe would miss.

Also scopes the sticky-toast default (item 5): reverted the blanket
"all error toasts are sticky" default, which had no container cap or
eviction, back to a flat 3s; the one message that needs a moment to
read (a failed custom-model apply) now passes an explicit
duration: 0 at its own call site.
