fix(web): usable past-conversation list, and search that finds past sessions

Two home-screen reports from @jordan8037310, both about history that is
present but unreachable.

#260 — "Resume Conversation" rendered 4 rows, then a button that appended
every remaining row into a `max-height: 240px` box, so 35 conversations
landed in a four-row scroll well with no ordering or filtering. Rendering
now goes through `_renderHistoryList()` over a cached corpus: 10 rows to
start, Show more/Show less that grows and shrinks the box (the height cap
is class-driven, `.history-list.expanded`), plus a filter box (name,
folder, #case label, prompts), a sort control (recent / name / folder,
pinned rows still first) and a shown-of-total count. A filter implies
expansion, so every match is visible, and the whole header hides as one
unit while a federated search is active. The A-Z sort keys off the same
string the row renders, since most rows are transcript-backed and carry
no session name at all.

#261 — the search box could not match a past project by folder name:
`harvestSources()` built its session corpus from the live in-memory map,
while past sessions come from `/api/sessions/unified` (lifecycle log +
transcript scan). Folding that scan into the request path would have cost
the search its no-filesystem-reads property, so the corpus arrives via a
bounded snapshot instead: `session-history-index.ts` is published as a
side effect of `/api/sessions/unified` (the home screen fetches it on
open, which is the same screen the search box lives on) and rebuilt
fire-and-forget, single-flight and TTL-guarded when a search finds it
stale. A result for a closed session now resumes the conversation rather
than selecting a tab that no longer exists, and is badged RESUME.

The snapshot is stored unscoped with a per-row owner and re-filtered
through canAccessOwned() on read, so multi-user sees exactly what
/api/sessions/unified exposes: own sessions only, host-wide transcript
history admin-only. Live rows are harvested first and win the dedupe.

Verified end-to-end against a real instance with 60 past sessions: cold
process answers its first search without history and its second with it;
folder-name queries return resume targets; clicking one posts the right
resumeSessionId + workingDir.

/**
* @fileoverview Issue #260 — the home screen's "Resume Conversation" list.
*
* With ~35 past sessions the list showed 4 rows, then a button that dumped every
* remaining row into a fixed 240px box, with no way to sort or filter. The fix
* moved rendering into `_renderHistoryList()` over a cached corpus, so what is
* worth pinning is the model, not the pixels:
* 1. the collapsed page is _HISTORY_INITIAL_COUNT rows, not 4,
* 2. "Show more" expands the LIST and marks the box expanded (the CSS cap is
* class-driven — without the class, expanding just deepens a scroll well),
* 3. filtering matches name / folder / case label / prompt, and implies
* expansion (hiding matches behind "Show more" defeats typing a filter),
* 4. sorting is alphabetical by name or folder, with pinned rows still on top.
*
* Loaded via `vm` against a stub CodemanApp with a fake DOM — same harness as
* resume-name.test.ts. `_buildHistoryItem` is stubbed: this pins WHICH rows get
* rendered and in what order, not how one row looks.
