Kailash Nadh 5fb7c6cfb0 Add support for automatic, idempotent DB migrations
- On boot, the app now checks if the DB version matches its
  expected version and refuses to start if there are pending
  migrations to be run.
- The new `--upgrade` flag runs data migrations from the last
  recorded migration (in the settings table) to the latest one
  in the binary.
- Migrations are DB/arbitrary logic functions in .go files in
  internal/migrations.
- All migration functions are idempotent.

Kailash Nadh 942eb7c3d8 Add settings UI and "hot reload" support to the app.
This is a major breaking change that moves away from having the
entire app configuration in external TOML files to settings being
in the database with a UI to update them dynamically.

The app loads all config into memory (app settings, SMTP conf)
on boot. "Hot" replacing them is complex and it's a fair tradeoff
to instead just restart the application as it is practically
instant.

A new `settings` table stores arbitrary string keys with a JSONB
value field which happens to support arbitrary types. After every
settings update, the app gracefully releases all resources
(HTTP server, DB pool, SMTP pool etc.) and restarts itself,
occupying the same PID. If there are any running campaigns, the
auto-restart doesn't happen and the user is prompted to invoke
it manually with a one-click button once all running campaigns
have been paused.

Kailash Nadh 022b35c4a7 Add support for sending 'opt-in' campaigns.
- Campaigns now have a `type` property (regular, opt-in)
- Opt-in campaigns work for double opt-in lists and e-mail
  subscribers who haven't confirmed their subscriptions.
- Lists UI shows a 'Send opt-in campaign' optin that
  automatically creates an opt-in campaign for the list
  with a default message body that can be tweaked before
  sending the campaign.
- Primary usecase is to send opt-in campaigns to subscribers
  who are added via bulk import.

This is a breaking change. Adds a new Postgres enum type
`campaign_type` and a new column `type` to the campaigns table.

Kailash Nadh 871893a9d2 Add double opt-in support.
- Lists can now be marked as single | double optin.
- Insert subscribers to double opt-in lists send out a
  confirmation e-mail to the subscriber with a confirmation link.
- Add `{{ OptinURL }}` to template functions.

This is a breaking change. Adds a new field 'optin' to the lists
table and changes how campaigns behave. Campaigns on double opt-in
lists exclude subscribers who haven't explicitly confirmed subscriptions.

Changes the structure and behaviour of how notification e-mail routines,
including notif email template compilation,  notification callbacks for
campaign and bulk import completions.
