* fix(categorization): connect card descriptors to counterparty history
suggest_categories returned no signal for recurring card merchants
(reported: Anthropic booked to 5420 fourteen times, zero suggestions).
Three compounding causes, all fixed:
- normalizeCounterpartyName() now reduces card-network descriptors to
their merchant segment ("ANTHROPIC* CLAUDE SUB SAN FRANCISCO" ->
"anthropic"; "PAYPAL *SPOTIFY" -> "spotify"), so monthly per-charge
tails stop splintering one merchant into unmatchable variants. SQL
mirror normalize_counterparty_key() updated in lockstep (migration
20260721140000), keeping the ledger-context template join exact.
- New token_subset match tier bridges templates learned from manual
bookings ("Claude Dec" -> "claude") to bank descriptors containing
the token, and card-core descriptors to legacy splintered templates.
Guarded by a distinctive-token filter so generic/geo words never
match on their own.
- Merchant history falls back to description when merchant_name is
null: card purchases never carry merchant_name, so the history path
was structurally blind to exactly the transactions that need it.
History keys now share the counterparty-template normalization and
the 200-row window is ordered by recency.

* fix(categorization): guard single-token matches, anchor history on original_description
Review follow-ups (CodeRabbit on #1095):
- token_subset tier: a single shared distinctive token now also requires
occurrence_count >= 3 on the template, so a template named after a
common word or first name (one prior booking) cannot vacuum up
unrelated transfers ("SWISH ANDERS JOHANSSON"). Multi-token agreement
stays unrestricted; the Claude/Anthropic case (14 bookings) is
unaffected.
- merchant history keys on original_description ?? description: the raw
bank descriptor is immutable while description is a user-editable
working title, so renaming a transaction no longer severs its history
link for future recurring charges.

* chore(migrations): re-timestamp card-descriptor migration after prod moved past it
Prod applied 20260721144311 (#1101) through 20260721201747 (#1104) while
this PR was open; 20260721140000 would sort before them and risk being
skipped by out-of-order auto-apply at merge. Not yet applied to prod, so
renaming is safe; the preview branch re-applies idempotently
(CREATE OR REPLACE).
