This commit refactors the source configuration and loading mechanism to
use a dynamic registration pattern. Each source package now registers
itself with a central registry via its init() function.
The server configuration code uses this registry to decode and
initialize sources, decoupling it from specific source implementations
and simplifying the addition of new sources.
Key changes:
- Introduced `sources.Register()` and `newConfig()` constructor in each
source package.
- Moved source package imports to `cmd/root.go` as blank imports to
trigger `init()` functions for self-registration.
- Removed direct imports of specific source packages from
`internal/server/config.go`.
- Renamed `SourceKind` constants to `Kind` within each source package.
- Updated tests to use the new `Kind` constants and reflect registration
changes.

User agent will be set as "genai-toolbox/" + versionString.
Instead of a panic, Toolbox will throw an error if the source fail to
retrieve `user agent`.
This will also be consistent with setting and getting logger from
context.
This only checks within `SourceConfig`, `ToolConfig`, and
`AuthSourceConfig`.

Add user agent to cloud databases that provides us anonymized data
request count, number of users, number of projects, and other
environment settings.
User agent is using the format: `genai-toolbox/$version+metadata`
1. `sql/database` provides a `Scan()`interface to scan query results
into typed variables. Therefore we have to create a slice of typed
variables (types retrieved from rows.ColumnTypes()) to pass them into
`Scan()`. Using []byte works but makes the printing result different
from other tools (e.g [1] instead of %!s(int32=1)]
2. MS SQL supports both named (e.g @name) and positional args (e.g @p2),
so we have to check if the name is contained in the original statement
before passing them into `db.Query()` as either named arg or as values.
