Consume the new `fee` flag from the API: bank service/maintenance fees
are dropped from the transaction list, expense totals, the categorize
review queue, and the recurring estimate — the user treats them as noise,
like transfers.
Card charges were showing as raw masked-card strings with no suggestion.
prettyMerchant/suggestCategory now extract the merchant after the last
:MCI: segment (e.g. "...:MCI:ANTHROPIC 1" -> "ANTHROPIC"), and the
keyword map is grounded in real uncategorized merchants (card-processed
software/cloud, cross-border marketplaces, local lenders, grocers,
carriers, electronics, gaming). Also fixes a Cyrillic \b word-boundary
bug (JS's \b never matches non-ASCII text) and moves CAFE/КАФЕ to the
Coffee rule instead of Food & Drink.
Adds a month navigator and category filter chips to the Тооцоо list, plus a
categorize-review flow at /accounting/review for bulk-assigning categories to
uncategorized merchants (grouped by matchKey, biggest spend first).
