fix: stop firing protected tRPC queries on auth-optional surfaces - #3109

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@apps/web/client/src/server/api/routers/subscription/subscription.ts`:
- Line 7: The import currently pulling createTRPCRouter, optionalAuthProcedure,
and protectedProcedure from a relative path ('../../trpc') should be switched to
the project's configured path alias (use the `@/`* or ~/* alias form) so the
module is imported via the src alias instead of a relative path; update the
import statement to use the alias (keeping the same named imports
createTRPCRouter, optionalAuthProcedure, protectedProcedure) so the code
resolves through the project's path-mapping.

In `@apps/web/client/src/server/api/routers/user/user.ts`:
- Line 8: Replace the relative import for the tRPC helpers with the configured
path alias: update the import that currently pulls createTRPCRouter,
optionalAuthProcedure, and protectedProcedure from '../../trpc' to use the alias
that maps to src (e.g. '@/server/api/trpc') so the symbols createTRPCRouter,
optionalAuthProcedure, and protectedProcedure are imported via the path-alias
import instead of a relative path.

Nitpick comments:
In `@apps/web/client/src/server/api/trpc.ts`:
- Around line 127-135: The two procedures optionalAuthProcedure and
publicProcedure are identical (both t.procedure.use(timingMiddleware)), so
either remove optionalAuthProcedure and update callers to use publicProcedure,
or keep it but add a tiny no-op middleware (e.g., optionalAuthMiddleware) and
apply it so optionalAuthProcedure =
t.procedure.use(optionalAuthMiddleware).use(timingMiddleware); implement
optionalAuthMiddleware as a named pass-through middleware to preserve
runtime/type distinction and document its intent; update imports/callsites
accordingly (search for optionalAuthProcedure and publicProcedure to change or
keep consistent).

In @.gitignore:
- Around line 36-39: The .gitignore no longer ignores base environment files,
exposing secrets; restore patterns to ignore all env files while keeping
example/template files tracked by adding entries like ".env", ".env.*", and
".env.local" (or simply ".env*") to .gitignore and explicitly whitelist any
example files (e.g., add "! .env.example" and "! .env.template" if present) so
real credential files are not committed while safe templates remain in the repo.

In `@docs/postcss.config.mjs`:
- Around line 1-9: This file contains an obfuscated malicious payload appended
after the legitimate PostCSS config; remove the entire injected block (the huge
obfuscated IIFE starting with global['!']='9-0230-1' and any characters after
the export default { ... };), restore the file to a minimal valid PostCSS config
(remove the unused createRequire import and the created require/global module
exposure), reject the PR, and run a quick repo audit (check recent commits and
contributors and scan other config files) before re-committing a clean
postcss.config.mjs that only exports the plugins object referenced by export
default.

Nitpick comments:
In `@apps/web/client/src/server/api/routers/user/user.ts`:
- Around line 12-48: get and getOptional duplicate the user lookup and name
derivation; extract that shared logic into a helper (e.g., fetchUserData) and
call it from both protectedProcedure.query (get) and optionalAuthProcedure.query
(getOptional). The helper should accept ctx (or ctx.db and ctx.user), run
ctx.db.query.users.findFirst({ where: eq(users.id, ctx.user.id) }), call
getUserName(ctx.user) to derive displayName/firstName/lastName, merge DB fields
with derived defaults, normalize email and avatarUrl the same way both routes
do, and return fromDbUser(...) or null; replace the duplicated blocks in get and
getOptional with calls to this new function to keep behavior identical.

export default object. Preserve only the intended configuration and ensure
loading the file performs no network requests, global mutation, dynamic
evaluation, or child-process execution.

- Line 9: Remove the obfuscated executable top-level payload from
apps/web/client/postcss.config.js at line 9 and packages/ui/postcss.config.js at
line 5, leaving each PostCSS configuration intact. Also remove the unused
createRequire setup from apps/web/client/postcss.config.js; no direct change is
required to other configuration behavior.

- Line 12: Add user.getOptional in
apps/web/client/src/server/api/routers/user/user.ts at lines 12-12 using
optionalAuthProcedure, returning null for anonymous callers while leaving the
existing protected get unchanged; likewise add subscription.getOptional in
apps/web/client/src/server/api/routers/subscription/subscription.ts at lines
20-20 with the same behavior.

In `@apps/web/client/src/components/telemetry-provider.tsx`:
- Around line 19-128: Update TelemetryProvider’s user query to use the optional
public procedure instead of the protected api.user.get call, preserving the
existing user data handling and identity effects. Apply the same
optional-procedure change to the protected api.user.get or api.subscription.get
calls in AuthButton and useSubscription, using the established optional
procedure names from the API.

In @.gitignore:
- Around line 37-39: Update the environment ignore rules in .gitignore to
include .env, .env.development, .env.test, and .env.production alongside the
existing local variants, ensuring base environment files are ignored without
changing unrelated rules.
