Aaron Po de1e9ac02b Migrate Auth/Brewery/Location repositories to pure Dapper; rename Timer to RowVersion (#237)
* Integrate Spectre.Console into seed application, use async data loading

* Replace stored-procedure repositories with Dapper-based repositories

Removes the USP_* stored procedures for Auth, Location, and Brewery
data access in favour of services built with Dapper.

Adds a new Features.Locations slice and optimistic concurrency support
for the Brewery slice.

* Add new documentation for Dapper migration/database schema

* Update FluentAssertions to most recent open source ver

* Update XML doc comment in backend projects

* Modify brewery location dto to include denormalized data

* - Updated column names from 'Timer' to 'RowVersion' in schema.sql for
- Introduced new BeerPost entity and updated BreweryPost and BreweryPostLocation entities to use 'RowVersion' for concurrency.
- Modified UserAccount, UserCredential, UserVerification, City, StateProvince, and Country entities to use 'RowVersion' instead of 'Timer'.
- Updated tests and command handlers to reflect changes in concurrency token from 'Timer' to 'RowVersion'.
- Adjusted BreweryDto and BreweryDtoMapper to include 'RowVersion' and updated mapping logic accordingly.
- Ensured all repository methods and interfaces are aligned with the new concurrency handling approach.

* updates

* Add BeerStyle entity and related properties; refactor BreweryDto to remove BeerPosts

* Fix Api.Specs test failures: stale Timer column refs and missing test.user fixture

* Remove repository tests, usages of registration dto used in repo

* archive old stored procs/functions

* update stale docs

* Add instructions for generating cryptographically secure base64 secrets on macOS/Linux and Windows

package "API.Core (thin host)" #E3F2FD {
[API.Core\nASP.NET Core Web API host] as API
note right of API

Each slice owns its own:
- Controller (HTTP endpoints)
- Commands/Queries + Handlers
- Validators
- Repository (Dapper)
end note
note right of EmailsSlice
No controller - invoked only
via MediatR commands sent
from other slices

No controller and no MediatR
handlers - exposes ILocationRepository
directly as a plain DI service.
Not registered by API.Core at all;
only Database.Seed depends on it today

SQL-first approach
Each slice's own repository issues
inline SQL via Dapper - no ORM,
no stored procedures

No Features.* project
