cli: add name, image and relay server address flags (#6944)

* cli: add --relay-address-server option for chat relay

New CLI flag --relay-address-server SERVER selects the SMP server used
for the chat relay address link created at startup. Only valid together
with --relay; errors out otherwise.

Threads Maybe SMPServerWithAuth through APICreateMyAddress to the new
agent createConnection parameter.

* cli: add --user-display-name option

Selects or creates the active user non-interactively:
- no active user: create one with the given display name
- active user with matching localDisplayName: continue
- active user with different name: exit with error

Mutually exclusive with --create-bot-display-name.

* cli: add --user-image-file option

Sets the active user's profile image from a .png/.jpg/.jpeg file at
startup. Reads file, base64-encodes as data URL, and updates the user
profile directly in the DB - no notification is sent to existing
contacts. Skips the update if the stored image already matches.

Requires --user-display-name.

* cli: address PR review comments

- rename APICreateMyAddress field srv_ to server_
- extract repeated `loop` and putStrLn from createActiveUser via
  prompt where-clause
- fuse u_ inspection: validate active user display name in the same
  case that creates the user when missing

* cli: enforce profile image size limit in --user-image-file

Reject the file if the encoded data URL exceeds 12500 bytes - matches
the cap mobile and desktop UIs pass to resizeImageToStrSize for profile
images. Without this, oversized images would be silently set on the
user profile.

* core: validate profile image size in chat commands

Enforced in CreateActiveUser, updateProfile_, newGroup, runUpdateGroupProfile
via checkProfileImageSize; max 12500 bytes (matches mobile UIs).

* fix: thread new ChatOpts/CoreChatOpts fields through bot/test constructors

* bots/docs: filter hidden params before type introspection

Hide APICreateMyAddress server_ field so the bot doc generator does not
try to introspect SMPServerWithAuth (an unregistered type).

* core: validate full encoded profile size

Add checkProfileSize / checkGroupProfileSize that encode the full
ChatMessage and check against maxEncodedInfoLength, so a long
displayName/bio combined with a near-max image is also caught at
command time instead of failing later at send time with CEException.

Run alongside the existing checkProfileImageSize (image-only cap of
12500 bytes, matching mobile UIs) in CreateActiveUser, updateProfile_,
newGroup, runUpdateGroupProfile. Update genProfileImg to fit the cap.

* cli: add --headless option for chat relay

Skips interactive prompts (relay address creation, display name) so the
chat relay can run non-interactively as a service. Requires --relay;
creating a new profile also requires --user-display-name.

* test: cover profile image size limit and address server

Adds tests for two new capabilities:
- profile image size validation rejects oversized images
- /_address with a server pins the address to the requested SMP server

* core: update simplexmq (pass optional SMP server to prepareConnectionLink)

* cli: add /set profile image file, fix image flag

Add "/set profile image file <path>" command to set the profile image
from a .png/.jpg/.jpeg file in a running session.

Make --user-image-file create-only: for an existing user it now no-ops
with a note instead of failing with "chat not started" (the update ran
before the chat controller was started).

* core: unify image loading and profile size checks

- loadImageFile (CLI) and readProfileImageFile (command) now share one
  loadImageData; removes the duplicated mime/base64 encoding and its
  decodeUtf8/safeDecodeUtf8 divergence. A missing --user-image-file no
  longer crashes with an uncaught IOException, and empty files are rejected.
- checkProfileSize/checkGroupProfileSize share checkInfoSize.
- --relay-address-server/--headless requires-relay checks use
  errorWithoutStackTrace, matching the adjacent validation (no callstack dump).

* bots/docs: document UpdateProfileImageFromFile as a CLI command
