SCAL-331020: Add Spotter analyst list/default actions and analystId config

[bahetirisabh]

Summary

Two additions for the Spotter Analyst experience, targeting ThoughtSpot 26.10.0.cl / SDK 1.53.0.

1. Two new Action enum members

SpotterAnalystList = 'spotterAnalystList',
SpotterDefaultAnalyst = 'spotterDefaultAnalyst',

They control the analyst list ("Show all") and the default Spotter analyst entry. These flow through the existing hiddenActions / disabledActions / visibleActions arrays, so there is no new plumbing — the enum entries just give hosts types and autocomplete instead of raw strings.

2. New analystId field on SpotterEmbedViewConfig

/** Pins the embed to a single spotter analyst. Implies no default Spotter and no "Show all". */
analystId?: string;

Top-level on the view config, serialized into the iframe URL via a new Param.AnalystId = 'analystId' the same way other embed params are, so the FE can read it off embedParams.analystId. setParamIfDefined omits it entirely when unset, so the URL is unchanged for hosts that don't use it.

Note on the typedoc diff

static/typedoc/typedoc.json is regenerated in a separate commit. The diff is large, but ~95% of it is mechanical id renumbering and line shifts caused by inserting symbols into types.ts.

Beyond this PR's own symbols, the regeneration also picks up drift already on main from commits that did not regenerate the docs:

• preRenderConfig from SCAL-325090 Add PreRenderConfig to control iframe z-index #603
• the enum-name corrections from fix(docs): correct enum member names in SDK doc examples #615 — EmbedEvent.customAction to CustomAction, EmbedEvent.DrillDown to Drilldown, ListPageColumns.Favorite to Favorites, AuthEvent.SUCCESS to AuthStatus.SUCCESS, and removal of the HostEvent.ScheduleList examples (that member does not exist)

Verified no documented symbol is lost by the regeneration: a symbol-set diff of old vs. new is 0 removals and 4 additions (SpotterAnalystList, SpotterDefaultAnalyst, analystId, preRenderConfig).

Test plan

• Added URL assertions for analystId (present when set, absent when not).
• Added both new actions to the existing hidden/disabled it.each tables in conversation.spec.ts.
• conversation.spec.ts: 75/75 passing.
• Full SDK suite: 1653 passed, 44/45 suites (the single failure is a stale local untracked sage.spec.ts, not part of this branch).
