feat(ui): book browse field registry, facet and sort query helpers

[alexhb1]

Description

This builds on the last PR with the book-specific side of the browse items. Primarily, this is a single registry describing each book data field, including it’s sort / facet / table column. This also expands the query layer so that the facet request returns the server’s sort tokens.

Changes

Book browsing:

• book-browse-fields.ts - This registers each field with any of the following: i18n label, facet info (Key, whether it’s a numeric range, value order and any buckets, whether it’s a shelf/library, whether it’s open by default in the filter rail), its sort info (key, what group, default direction, what icon it uses, whether it adds extra detail to the cards when active), and column info (what group, default visibility and width, whether it’s hideable, plus its value formatting)
• book-browse-columns.ts - Handles table column options and sections for the column picker, the sizing, the sort key for each column, the cell value formatting, and handling a user’s saved column preferences.
• book-browse-facet-definitions.ts - Adapts the book fields for shared/browse/facets.ts, includes resolving shelf/library names for the filter options.
• book-browse-sort.ts - Sort options from the backend, direction icons, and whether a sort key has a detail line on the cards.
• book-value-labels - This is for any “buckets” based on formatted numerical data from the facets, specifically the metadata match score bands for books.

Misc:

• book-query-params.ts - Adds helpers for the URL form of facets and sort, so that the book browser can show these as items in the URL.
• book-query.service - The facet query now also returns the backend sort tokens. This also includes the random sort handling to keep the seed consistent in normal use.
• adds the missing backend sort and filter options (audible and lubimyczytac ratings)

Walkthrough

The PR adds a metadata-driven book browse layer. It separates facet and sort results, adds validated query-token handling, defines book field and facet registries, supports configurable columns, and adds display-formatting utilities.

Changes

Book browse data flow

Layer / File(s)	Summary
Browse response and query-service flow frontend/src/app/core/data/browse-*.ts, frontend/src/app/features/book/data/book-query.*	Browse responses now return separate facets and sortTokens. The query service uses this result and adds seeded first-page loading and query reset support.
Book field and facet registry frontend/src/app/features/book/browse/book-browse-fields.ts, frontend/src/app/features/book/browse/book-browse-facet-definitions.ts, frontend/src/app/features/book/model/book-value-labels.ts, frontend/src/app/features/book/data/book-response.models.ts	Book fields now register facet, sort, column, label, grouping, and value metadata. Facet definitions and match-score bands use this registry.
Facet and sort query handling frontend/src/app/features/book/data/book-query-params.*, frontend/src/app/features/book/browse/book-browse-sort.*	Facet and sort tokens are parsed, validated, serialized, filtered, and mapped to book query terms.
Column display and formatting helpers frontend/src/app/features/book/browse/book-browse-columns.ts, frontend/src/app/shared/util/date-format.ts	Column preferences, visibility, grouping, sizing, values, and display formatting are centralized in reusable helpers.

92-95: 🩺 Stability & Availability

Keep the current error propagation for the facets query.

getMapped() returns the lastValueFrom() promise directly. HttpClient errors reject the query function, and QUERY_DEFAULTS.retry receives the original HttpErrorResponse for transient-error retries. Adding catchError without an application error contract would change this behavior unnecessarily.
